Hi, does anyone know how to stop my for loop overwriting? I need my answer to be a matrix with each element being a 2x2 matrix also.

[M,N] = size(MagGridForceAX); % Establish dimensions for row and column loop counters

for i = 1:M

for j = 1:N

% Creates coefficients for the simultaneous equations of F1 and F2

% based on sum of x and sum of y forces equalling zero

CoefficientMatrix = [MagGridForceAX(i,j) MagGridForceBX(i,j); MagGridForceAY(i,j) MagGridForceBY(i,j)]

% Forces Matrix solving for forces in beams in each x and y

% coordinate

ForcesMatrix = CoefficientMatrix\P;

end

end

[Walter Roberson]

 ForcesMatrix{i, j} = CoefficientMatrix\P;

The result will be a cell array that contains numeric arrays.

You could also do

ForcesMatrix(:, :, i, j) = CoefficientMatrix\P;

The result would be a 2 x 2 x M x N numeric array.

Thank you very much Walter Roberson, that works perfect.
