how to cast matrix into parse block diagonal system in matlab

To cast a matrix into a block diagonal system in MATLAB, you can use the blkdiag function. Here's how you can do it:

main.m
% Create a sample matrix
A = [1 2 0; 0 2 3; 0 0 4];

% Cast the matrix into a block diagonal system
B = blkdiag(A, A, A);

% Display the block diagonal matrix
disp(B);

In this code snippet, A is the sample matrix that you want to cast into a block diagonal system. The blkdiag function is used to form a block diagonal matrix B by repeating matrix A along the diagonal.
