Taking Absolute value of a cell arrray

19 views (last 30 days)
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);
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);
