[QUESTION] command names on History & CAS MODE VIEW - compsystems - 12-07-2016 03:16 PM Hello hp-prime community On CAS MODE & "Textbook Display on" or pretty-print. Why the command names are "renamed" to uppercase? Disabling "Textbook Display off" Is shown as it should be The are commands that are "renamed" to uppercase TYPE, DIM EVAL For the following case (LEFT CMD), it display the names correctly left(a = b) -> a LEFT("a = b",3) -> "a =" RE: [QUESTION] command names on History & CAS MODE - compsystems - 12-21-2016 06:07 PM Another case with ALGEBRAIC input mode on va:=[a,b] -> [a,b] Lowercase command abs(va) -> |va| -> [abs(a),abs(b)] // ok, Absolute value of each element Uppercase command ABS(va) -> |va| -> v(a^2+b^2) // ok, but it is displayed with the same symbol in the history this causes an output contradiction when copying screenshots into guides, texts etc. Should be displayed in the history as ||va|| PS: Diff, & (') is not seen in (typeset math) vd:=[f(x),g(x)]; ve:=[x(t),y(t)]; vd' -> diff(vd) -> [diff(f(x),x),diff(g(x),x)] diff(ve,t) -> [diff(x(t),t),diff(y(t),t)] All derivative representations must be displayed en Pretty-Print RE: [QUESTION] command names on History & CAS MODE VIEW - Tim Wessman - 12-21-2016 07:50 PM Because a list of names of commands that were "identical" was created. The idea was that it would create less confusion instead of dim vs DIM and so on. However, that has turned out to not be the case - especially as the CAS has changed, or had functionality that was not expected. It will probably be removed at some point to stop these posts. RE: [QUESTION] command names on History & CAS MODE VIEW - compsystems - 12-21-2016 10:23 PM The double functionality is valid and I agree ABS vs abs The problem is only visualization within the history view with "Textbook Display on" & ALGEBRAIC input mode Because copying the expression to the input line is renamed. Please try the following Enable the ALGEBRAIC input mode & "Textbook Display off" abs([a,b]) → [abs(a), abs(b)] // ok [up][up][copy] abs([a,b]) → [abs(a), abs(b)] // ok but Enable the TEXTBOOK input mode & "Textbook Display off" abs([a,b]) → ABS([a,b]) → √(a^2+b^2) This is not logical, the same input two different answers Another case CAS MODE MAKEMAT(0,10); -> Error: Bad Argument Type" Why? makemat(0,10); ->[[0,0,0,0,0,0,0,0,0,0]] makeMat(0,10); -> [0,0,0,0,0,0,0,0,0,0]; // ok =) mat1:=makeMat(0,10); -> [0,0,0,0,0,0,0,0,0,0]; // ok =) mat1(1):=a; -> [a,0,0,0,0,0,0,0,0,0]; // ok =) mat1(10):=j; -> [a,0,0,0,0,0,0,0,0,j]; // ok =) mat1[2]:=b; -> [a,b,0,0,0,0,0,0,0,0]; // ok =) mat1[2]; -> b // ok mat1(2); -> b // ok dim(mat1); -> 10 // ok DIM(mat1); -> {10} // ok DIM(mat1)[1]; -> 10 // ok DIM(mat1)(1); -> 10 // ok MAKELIST(0,X,1,10); -> {0,0,0,0,0,0,0,0,0,0} // ok makelist(0,X,1,10); -> [0] Why? makeList(0,X,1,10); -> Error: Bad Argument Type" Why? list1:=MAKELIST(0,X,1,10) -> {0,0,0,0,0,0,0,0,0,0} // ok dim(list1); -> 10 // ok DIM(list1); -> {1,1,1,1,1,1,1,1,1,1} // ok mat0:=MAKEMAT(0,3,4) -> [[0,0,0,0],[0,0,0,0],[0,0,0,0]] // ok HOME DIM(mat1) -> {10} dim(mat1) -> {10} DIM(mat1)[1] -> {[10]} -> 10 DIM(mat1)(1) -> {10} ? inside program (HOME) local elements:=dim(mat1)[1]; // error or local elements:=dim(mat1)(1); // error for aux_index_i from 1 to dim(a)[1] do // error
