Place the above code in a file called ‘mtimes.m’ and save this file in a directory with name ‘@int32’. This directory must be placed in a directory which is on the MATLAB path but do not add ‘@int32’ to the MATLAB path. This will give you the feature of multiplyin...
Finally, you are printing arr_2 to verify that it is a 2x2 array. Now you should see what happens when you change a value in arr_2. Like in the MATLAB example, you should change the upper left element of arr_2: Python In [5]: arr_2[0, 0] = 10 In [6]: arr_2 Out[6]...
A matrix has rows and columns; when we want to multiply 2 matrices, the number of columns and rows matters for it to be possible. We describe matrices to their rows and columns, e.g., a 2 x 4 matrix has 2 rows and 4 columns. With all this information, the first matrix’s(left ...
for k = 1:max_iter % Multiply matrix A with vector x y = A * x; % Normalize the vector x = y / norm(y); % Compute the Rayleigh quotient (dominant eigenvalue) lambda = x' * A * x; % Check for convergence if abs(lambda - lambda_old) < tolerance fprintf('Converged in %d ...
