Value Interpolation.

A matrix (1:400) has some value at 1 followed by 7 zeros then value at 9 followed by 7 zeros and so on uptil 400. To be more clear the sequence is like 1+i,0,0,0,0,0,0,0,-1+i,0,0,0,0,0,0,0.....-1-i,0,0,0,0,0,0,0. How to make this sequence as 1+i,1+i,1+i,1+i,1+i,1+i,1+i,1+i,-1+i,-1+i,-1+i,-1+i,-1+i,-1+i,-1+i,-1+i. Please let me know if anyone know this. Thanks for your time.

Answer 1

A = your_matrix;
B = reshape(repmat(A(1:8:end),7,1),1,[]); 
%extract values we care about/copy 'em/reshape to vector
