Problem 43284. Form a square matrix from four square sub-matrices
Create a square matrix, y, from 4 square sub-matrices that will be constructed (x1, x2, x3, x4):
y = [x1 x2; x3 x4];
The size of each sub-matrix will be n, while given values should be applied to each sub-matrix.
- 1st sub-matrix: n1 on the main diagonal with all other elements equal to 0
- 2nd sub-matrix: all elements equal to n2
- 3rd sub-matrix: all elements equal to n3
- 4th sub-matrix: same as the first but with diagonal elements equal to n4.
For example, with n=2, n1=1, n2=2, n3=3, and n4=5:
y = [1 0 2 2; 0 1 2 2; 3 3 5 0; 3 3 0 5];
