Hello,
i am a postgraduate student in Applied Informatics and i am using maxima
about a month.
I have problem using some functions of maxima and i will need your help.
The functions that i cannot understand are these: fft, ifft, dgesvd and
gamma.
1) fft
I would like to do compute this:
x: makelist(i*random(1000),i,1,100);
b:fft(x);
but i get an error.
I used to perform this operation in matlab like this, but i can't figure out
how this function works.
2) ifft
I would like to do compute this:
x: makelist(i*random(1000),i,1,100);
b:ift(x);
but i get an error.
3) dgesvd
h [i, j] := (1 + i*random(1000) + j)/(j*random(1000))+random(1000);
x: genmatrix(h,10,10);
b: dgesvd(x);
but again i get an error.
4) gamma
h [i, j] := (1 + i*random(1000) + j)/(j*random(1000))+random(1000);
x: genmatrix(h,10,10);
b: gamma(x);
but again i get an error.
I use Maxima 5-16.3 under Windows.
Thank you anyway,
Nick
