write a function that does the following calculation on an input: --if the input is a square matrix square, output the determinant in matlab

main.m
function det = calcDeterminant(matrix)
    % Check if the matrix is square
    [nRows, nCols] = size(matrix);
    if nRows ~= nCols
        error('The input matrix must be square!');
    end

    % Calculate the determinant
    det = det(matrix);
end
