RE: Bode/Nyquist/Nichols plot.....Fully functional

RE: Bode/Nyquist plot.....
Okay, I get it now.
I tried BODE(-1,1,[1],[1 0.2 1]) and got {5}
View-->start takes me to an empty home screen.
View-->Nyquist, Magnitude and Phase don't do anything....
edit1: I was trying with Statistics 1Var, just tried with Statistics 2Var and same result.

What am I missing?

Edit: Can't get it to compile without Sintax error on physical Prime. And my Prime is just formated, in English. Copied the 2-Var Statistics, renamed it to Statistics_2Var_Copy and on HP Connectivity kit went to Program tab for the Statistics_2Var_Copy app, and replaced the code with the proper one.
Did the same thing on Virtual Calculator and got no sintax error (No errors in program).............

RE: Bode/Nyquist plot.....
App is based on Statistics_2Var_Copy.
recompile it on your calculator...check for bug (no bugs)and then exit.
launch the App again, home screen enter your BODE(-1,1,[1],[1 0.2 1])
View and choose a plot and then hit PLOT to plot it.
to plot another graph back out to home and hit VIEW for options.
View >> Start/Info will refresh it
hit View>> (for options)
works here.....

On just formated Virtual Prime, did just that, and when hitting PLOT button it shows "S1 - Error: Statistics data size not equal":

View-->Start/Info, takes me to an empty white page. I hit View again, and the previous page shows up again (the one with the BODE[.....]) so I hit View once again, choose Niquist for instance, nothing happens, hit plot and this shows up:

hit Escape and this shows up:

and if I hit Symb this is what comes up:

RE: Bode/Nyquist plot.....
Finally...the bode code wasn't correct, I was copy pasting it from the web, that's why I was getting {5} instead of something like this:

So now I'm trying this transfer function:

But this is what I get:

What exactly are the f1 and f2 cells for on the bode code?

RE: Bode/Nyquist plot.....Fixed
BODE(.01,100, [1],[1 1])
.1 and 100 are the frequency range you want to analyze.
all plots/bode() executions shd be entered from Home screen.
Use VIEW>> {Start/Info, Magnitude, Phase, Nyquist, Nichols} HOME SCREEN
VIEW>>Start/Info (refreshes Statistics_2Var_Copy parameters...hit any Key to get You to Home Screen again)
Use VIEW>> {Start/Info, Magnitude, Phase, Nyquist, Nichols} again for the same BODE().
use soft Menu zoom (auto-scale)to zone in on plots. (just because i can't graphs to center on the screen) help needed on that!!!
This App is based on Statistics_2Var_Copy.
You need to recompile before your first use of this App.
Code:
 Tf(); BODE(); Xmi,Xma; VIEW "Start/Info",START() BEGIN C1:={}; C2:={}; S1:={'C1','C2','1','13'}; STARTVIEW(6,1); WAIT(); STARTVIEW(-1,1); END; export BODE(Xmi,Xma,num,den) BEGIN local num:=poly2symb(num,"*x"); local den:=poly2symb(den,"*x"); expand(num/den)▶F1; makelist(X,X,1,1000,1)▶L9; L1:=ALOG(LOG(Xmi)+(L9-1)*(LOG(Xma)-LOG(Xmi))/1000); Statistics_2Var_Copy.Xmin:=(Xmi); Statistics_2Var_Copy.Xmax:=(Xma); F2:=20*LOG(CAS.ABS(F1)); L2:=Tf(L1); L7:=20*LOG(ABS(L2)); L3:=ARG(L2)*180/pi; L4:=IM(L2); L5:=RE(L2); END; EXPORT Tf(x) BEGIN L2:=(F1(X)|x=L1); END; VIEW "Magnitude",Magnitude() BEGIN S1:={'C1','C2','1','13'}; C1:=LOG(L1); C2:=L7; Statistics_2Var_Copy.Xmin:=Statistics_2Var_Copy.Xmin; Statistics_2Var_Copy.Xmax:=Statistics_2Var_Copy.Xmax; Xtick:=1; Statistics_2Var_Copy.Ymin:= FLOOR(MIN(C2)+1); Statistics_2Var_Copy.Ymax:= CEILING(MAX(C2)+1); Ytick:=10; END; VIEW "Phase",Phase() BEGIN C1:=LOG(L1); C2:=L3; Statistics_2Var_Copy.Xmin:=Statistics_2Var_Copy.Xmin; Statistics_2Var_Copy.Xmax:=Statistics_2Var_Copy.Xmax; Xtick:=1; Statistics_2Var_Copy.Ymin:= FLOOR(MIN(C2)+1); Statistics_2Var_Copy.Ymax:= CEILING(MAX(C2)+1); Ytick:=5 END; VIEW "Nyquist",nyquist() BEGIN C1:=L5; L4▶C2; Statistics_2Var_Copy.Xmin:= FLOOR(MIN(C1)+1); Statistics_2Var_Copy.Xmax:= CEILING(MAX(C1)+1); Xtick:=.2; Statistics_2Var_Copy.Ymin:= FLOOR(MIN(C2)+1); Statistics_2Var_Copy.Ymax:= CEILING(MAX(C2)+1); Ytick:=0.2; END; VIEW "Nichols",Nichols() BEGIN C1:=L3; C2:=L7; Statistics_2Var_Copy.Xmin:= FLOOR(MIN(C1)+1); Statistics_2Var_Copy.Xmax:= CEILING(MAX(C1)+1); Statistics_2Var_Copy.Ymin:= FLOOR(MIN(C2)+1); Statistics_2Var_Copy.Ymax:= CEILING(MAX(C2)+1); Ytick:=10; END; PLOT() BEGIN STARTVIEW(1,1); END;

FOUND BUG COMPILING WITH DIGIT GROUPING
Hi again,

I just found out why I was getting Sintax error when compiling in my physical Prime (7820 fw.)
I realized that if you compile your program when the 123456,789 digit grouping is selected (the one we use in Spain), you get a Sintax error which doesn't happen if you have the default one (123,456.789).

I have to say the digit grouping feature was a really bad idea, it only has given me a lot of trouble :/

By the way, thanks for your last post, will try all that as soon as posible!

RE: Bode/Nyquist plot.....
Hi again, I didn't know f1 and f2 was the frequency range (rad/s). You typing [-1,1] and [-2,2] on some examples confused me since negative frequencies don't exist.

I've been trying to plot this:

and I got this:

But, I don't understand why the 'x' takes negative values, since that's the frequency axis. How am I supposed to read the frequency values, mate? Thanks in advance

RE: Bode/Nyquist plot.....
Use Trace to read values.....or Num key. (the numerical values are really spot on.)
remember is a log10 scale: values on the X-axis: values Trace on the X-axis shd be 10^(X-value) .(for magnitude,phase plots)
so your negative values on X-axis are pretty much fractions.
BODE(.1,10 [1],[1 1]) is what you really have to enter.

on the Info tab in Conkit just paste the below instructions and recompile the App, this will give you the info when u do start the App or press VIEW>>Start/Info:

Frequency response plots corresponding to G =

s + 1
------------
s^2 + 0.2 s + 1

BODE(ƒ1,ƒ2,[numerator],[denominator]) enter
BODE(0.01,100,[1 1],[1 .2 1]) enter
Use VIEW key for Plot selection

I haven't studied the graph, but some physicists argue that negative frequencies exist, much like negative distances or displacements. Consider for example a clock, with a second hand rotating clockwise. Apply a negative rotational force - the frequency that the second hands sweeps clockwise will reduce and eventually reach 0. continue to apply the force. The second hand will begin to sweep anti-clockwise at a positive frequency - or clockwise at a negative frequency, if you like. Just like walking -5m North really. Though perhaps it could be called something else, like we distinguish 5m distant (positive) from 5m North (signed).

This is a nice app -- I'm hoping someone can help with my user errors & setup...

I am unable to get the positive values on imaginary axis to display in the nyquist plots (basically anything > 0 on Y axis is not plotted). Positive / negative real values are okay. Is there a setting to change behavior?

<corrected above and deleted other question because it was previously answered>

Thanks!

RE: Bode/Nyquist plot.....
Thanks, it's not working for me but I'll keep playing as I'm sure I'm doing something wrong ( calculator is brand new and I'm coming from a 48)

Seems that the check box disappears as soon as I run nyquist plot and graph is the same.

On home screen I enter:

C3:=-C2 (it returns {} or contains data.I'm guessing depending on if I executed bode previously)

In the symbol screen, I replace the C0 with C1 and C2 with C3 as well as check the box

I then evaluate the bode expression and get the same results as before. If I check back in the symbol I see the check box has cleared but C1/C3 remain.

I'll keep playing, thanks for help
