Dear all, I have the following problem:
mydata{n}(m,l)
let say n=1:1:3; m=1:1:4 and l=1:1:100
I have many zeros in cell. How can I remove them:
the result for mydata{1}(:,:) looks like :
0.223811939491137 0.751267059305653 0.255095115459269 0.505957051665142

mydata{i} is a two dimensional matrix. What would be the result if you remove zeros from that? What would you replace them by?

This replaces the zeros with empty square brackets:
mydata = { 0.223811939491137 0.751267059305653 0.255095115459269 0.505957051665142

0.129906208473730 0 0 0};
zero_idx = bsxfun(@eq, [mydata{:}], 0);
mydata(zero_idx) = {[]};

On removing zeros...your matrix will be arranged into a vector.
% some random data
A = cell(3,1) ;
for i = 1:3
A{i} = round(rand(10,4)).*rand(10,4) ;
end
%%remove zeros
for i = 1:3
A{i}(A{i}==0) = [];
end
