taking the inverse of multiple matrix's

sigma is a 28x28x10 matrix, or 10 28x28 matrix's. I'd like to get the iverse of each of those matrix's and store them in mean_inverse, but it is saying "Warning: Matrix is singular to working precision. " What am I doing wrong?

Nothing. But some or all of the sigma matrices that you try to invert seem to be singular.

There are, however, arguments to be made that in practice using inv() is most often a mistake, that there are very often mathematically better methods that do not involve explicit calculation of the inverse of a matrix.

% Define the matrices
A = [1 2; 3 4];
B = [5 6; 7 8];
C = [9 10; 11 12];
% Create a cell array of the matrices
matrices = {A, B, C};
% Loop through the matrices and calculate their inverses
for i = 1:length(matrices)
inv_matrices{i} = inv(matrices{i});
end
% Display the inverse matrices
for i = 1:length(inv_matrices)
disp(['Inverse of matrix ', num2str(i), ':']);
disp(inv_matrices{i});
end
