How to perform the following operation ( M=M+thr*M.*(N*2-1);)in each column in matrix M?

M is matrix with size 14*128

N is random matrix with size 14*1

I tried the follwing code but it doesnt work.. Does any one has any idea how to run this?

thr=.05 ;    
N=rand(14,1) ;
for c=1:128
    M(:,c)=M(:,c)+thr*M(:,c).*(N*2-1);
end

thr=.05 ;    
M = rand(14,128) ; 
N = rand(14,1) ;
for c=1:128
    M(:,c) = M(:,c)+thr*M(:,c).*(N*2-1);
end

It didn't work in your case because, you have not defined the matrix M.

@KSSV, I have another saved Matrix M.
