Hello SDR community, I need some guidance into how vector manipulation works in GNU radio companion.
Suppose I have the following MATLAB/Octave code: Nf = 128; Nt = 2^10; F = zeros(Nt/2+1,1); idxs = (1:round(Nt/Nf)/2:Nt/2)+1 phi = 2*pi*rand(Nf,1); F(idxs,:) = sqrt(Nt)*exp(1i*phi); % can't figure out how to manipulate elements of F (vector object in GRC) What would be the most efficient (development time) way of implementing this? I have spent a couple of hours in GRC messing with vector blocks and I still can't find ways to manipulate indexes of vectors. Should I make a bare-bones template in GRC and add my own numpy code to get around block limitations? I feel like GRC was designed with streaming in mind. Vector and matrix manipulation seems really limited with GUI blocks unless I am missing something. Do most people write python code directly for non-streaming situations? Thank you for your time, Ali
