"cycle for" between matrix with a variable in the name
显示 更早的评论
Hi;
I have a series of matrix like A1, A2....AN and i want to perform an operation like
for i=1:N
B=B+A"i"(:,2)
end
how do i have to format the A"i"(:,2) part?
thank you

Can you dynamically create variables with numbered names like A1, A2, A3, etc.? Yes.
Should you do this? The general consensus is no. That Discussions post explains why this is generally discouraged and offers several alternative approaches.

Hi Andrea,
Refer to the example implementation:
N = 5; % Example no of matrix
A = {A1, A2, A3, A4, A5}; % Cell array containing matrices
% Initialize B
B = zeros(size(A{1}, 1), 1); % Assuming all matrices have the same number of rows
% Perform the operation
for i = 1:N
B = B + A{i}(:, 2);
end

A = zeros(size(B.C1,1),1);
for ii = 1:100
A = A + B.("C"+ii)(:,12);
end

"...I am working with struct of the type B.C1, B.C2....B.C100"
Rather than forcing pseudo-indices into the fieldnames it would be simpler and more efficient to use actual indexing.
