Hello,
I am getting this error: Operator '.*' is not supported for operands of type 'cell'.
Here my code:
for a=1:m %d->m
for b=1:m %d->m
for x=1:m
for y=1:m
BO=BO+B(a,b,x,y).*(kron(A_ax(:,:,x,a),B_by(:,:,y,b))); %this is the Bell operator
end
end
end
end
And b is coming from other code. I am converting it:
B=T(:,:,:,:);
B=cell2mat(B);
I really dont understand why I have this error and how I can solve it

Well, you need to check whether B is a cell array or not (it almost certainly is). Did your call to cell2mat work?

Hopefully after you read the FAQ, you'll have a better idea of what a cell array is, how it works, and how to use it: FAQ : What is a cell array? And you'll learn when to use braces, when to use parentheses, and when to use brackets.

If B is a cell array, try B{a,b,x,y} instead of B(a,b,x,y) to get the contents of the cell.

B is a cell array because when I tried to convert it, I am getting this error:
Dimensions of arrays being concatenated are not consistent.
Error in cell2mat (line 118)
ct{mref{:}} = cat(cdim+1,c{mref{:},:});
