Hey guys, thanks in advance,
I have this azimuth_compressed_matrix, defined by freq_azimuth(frequency) x azimuth. However I want to define this matrix only for values of freq_azimuth>0. Basically , in this example, I want to make a way to make this code I made automatic, is there a way?
k=find(freq_azimuth>0);
freq_azimuth2=freq_azimuth(4000:7999);
azimuth_compressed_matrix2=azimuth_compressed_matrix(:,4000:7999);

Your code does not use "k" anywhere, so the intention is not clear.

One more time, yet again, it's one of the most fundamental of MATLAB idioms/syntaxes that makes MATALB what it is -- <MatrixIndexingExample-Logical Indexing>
azimuth_compressed_matrix2=freq_azimuth(freq_azimuth>0);
Again, there's no need for find here...
