Here's the complete example code:

To create an nxn matrix in MATLAB, you can use the following methods:

: Best for viewing elevation levels or isolines of a 3D surface.

n = 5; % Define the size of the matrix matrix = rand(n); % Creates an nxn matrix with random values between 0 and 1

figure; contourf(X, Y, Z, 20); % Renders 20 filled contour levels colorbar; title('Filled Contour Plot of an N x N Matrix'); Use code with caution. 3. Customizing the Plot Appearance

MATLAB offers several built-in functions to create square matrices:

MATLAB plots can handle double-precision numbers, integers, and logical matrices.

matrix. Ensure your meshgrid matches the matrix shape exactly.
