Raise elements of cell arrays in the power of 2

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.

how i CAn raise the power of an single element of the array

[Jay shankar Nanda]

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.

You are right. However, I needed to create cell arrays in an earlier stage in order to avoid tens of repetitions and I am stack with the cell arrays.
