Those commands are fourier_an, fourier_bn, fourier_cn ...

I assume those will do what you are looking for?

yes, Tim!
I mean those commands, all three (cn is for the exponential series)...
So, they will be no more in the CAS, never in the next update?
Ok, then I must just my little program (see above), also if it would be better to have them integrated...

For me there few things that I could see missed in confront of my "old" HP 50g: these ones and the command "image" that in the HP50g is in the section "Linear Application" (with mkisom, ker...), for a matrix...
Another good thing to have would be "Directional Derivative" (see my post here)
For the rest Prime has already almost everything (excluding Graph3D and QPI, for example)
I'm adding only something to calculate inverse (pseudo inverse) of a matrix, and few other useful programs...

thank you,
