Taking Absolute value of a cell arrray

Hi

I want to take an absolute value of a cell array, but I am getting this error

"Unable to perform assignment because brace indexing is not supported for variables of this type."

I am attaching the file for which I want to take the absolute value and I am using this code

L = 128;  
for i =1:1:size(Numerical_FourierForce,1)
    for j =1:1:size(Numerical_FourierForce,2)
        P2{i,j} = abs(Numerical_FourierForce{i,j}/L);
    end
end

It is working if I remove the "L" from the loop, but I want to do it with it

Does anybody knows?

clear all
load NumericalFourierForce % note i haven’t seen your .mat file, shooting in the dark
L = 128; % make sure there isn’t any variable named L in the .mat file 
P2 = cell(size(NumericalFourierForce)); 
for ii =1:size(Numerical_FourierForce,1)
    for jj =1:size(Numerical_FourierForce,2)
        P2{ii,jj} = abs(Numerical_FourierForce{ii,jj}/L);
    end
end

Great! Thanks.. it worked

One more question, each cell has now 2 values, how can i seperate them into different cells

>> P2{1,1}

ans =

   41.2467
  164.1353

 num2cell(P2{1,1})

 cellfun(@num2cell, P2, 'un', 0)
