I'm very new to Gauss, so excuse my ignorance, since I used to work on Matlab
I have a code to run on a variable, but I can't know where the results, so any help please,
/* ** Procedure DDFT_FFT ** ** Computes Discrete to Discrete Fourier Transform. ** Uses Fast Fourier Transform (FFT) algorithm. Sample size may be changed (powers of 2). ** ** n : sample size ** srs : time series (n x 1) ** a : 1/n sum x(t) cos (w(i) t) for w(i) = 2 pi i/n and i=0,...,n-1 (real part) ** b : -1/n sum x(t) sin (w(i) t) for w(i) = 2 pi i/n and i=0,...,n-1 (imag part) */ proc (2) = DDFT_FFT(srs); local a,b,a2,b2,kwsom,test,n1,y; y=fft(srs); a=real(y); b=imag(y); retp(a,b); endp;

If you just ran that code snippet that you posted, there will not be any results. That code just defines a GAUSS procedure. A GAUSS procedure is a GAUSS function that can be called. Before you have any results, you will need to:
- Load or create some data
- Call some functions or use operators on the data
For example, this code will produce no output
proc (1) = double(x); x = 2 * x; retp(x); endp;
But this program will assign values to b and print the result to the screen
//Create a column vector a = { 1, 2, 3 }; //apply the 'double' procedure b = double(a); //print the output print b; proc (1) = double(x); x = 2 * x; retp(x); endp;
Take a look at the Tutorials page. And if you run these commands
examples_dir = getGAUSSHome()$+"examples"; print "You can find GAUSS examples in the "$+examples_dir$+" directory on your computer"; print "the example files will end with a .e file extension";
GAUSS will tell you where to find some example files to run.
