Hi everyone,
I have a cell array A of 2x100, where each element is a scalar and I want to raise in the power of 2. I have tried:
for k=1:2;
for t=1:100;
A2{k,t}=A{k,t}.^2;
end;
end;
But it doesn't work. Thanks in advance.

x={2,3,4};
>> x(2).^2
Undefined operator '.^' for input arguments of type 'cell'.
kindly tell how to access the input argumentand raise it to power

Like this?
A = 2x100 cell array of scalars
A2 = mat2cell(cellfun(@(x)x.^2,A),ones(1,2),ones(1,100));
SIDE NOTE:
Your posts seem to indicate that you have a lot of scalar data in cell arrays that you want to do basic matrix arithmetic/functions with. Is there a reason you have this data in cell arrays rather than double matrices? It would be a lot easier (and cleaner) to maintain this data as double matrices in your code rather than in cell arrays unless you have some specific reason to have the cell arrays.
