generate random matrix with selected determinant in matlab

main.m
% Set the matrix size
n = 3;

% Set the target determinant
det_value = 10;

% Initialize the determinant
det_matrix = 0;

% Generate a random matrix with the desired determinant
while det_matrix ~= det_value
    % Generate a matrix with normally distributed random numbers
    A = randn(n);

    % Multiply the matrix with a scalar to adjust the determinant
    multiplier = det_value / det(A);
    A = A * multiplier;

    % Calculate the determinant of the matrix
    det_matrix = det(A);
end

% Display the matrix and its determinant
disp('Random matrix with determinant 10:');
disp(A);
disp(['Determinant: ' num2str(det_matrix)]);
