Please how can I convert the some values of my cell array from 0 to NaN

Hi all,

I am intermediate user of MATLAB - I understand the basics and just a bit more.

I have a 43 x 25 cell array, having matrices of various sizes in each cell (for example: 2000 x 61, 4000 x 61 and others of approximate size). Some of these matrices have zero values that I need to convert to NaN.

Please I would appreciate your help.

A - your cell array.

for ii = 1:numel(A)
    A{ii}(A{ii} == 0) = nan;
end

An example:

a={zeros(1,12)}
a=cell2mat(a) 
a(a==0)=NaN
a={a}
celldisp(a)
