Remove zeros from cell

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?

Answer 1

[Star Strider]

This replaces the zeros with empty square brackets:

mydata = {  0.223811939491137   0.751267059305653   0.255095115459269   0.505957051665142
            0.699076722656686   0.890903252535798   0.959291425205444   0.547215529963803
            0.138624442828679   0.149294005559057   0.257508254123736   0.840717255983663

            0.753729094278495   0.380445846975357   0                   0
            0.053950118666607   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
