DiagUtility

This module contains useful routines related for diagonal matrices.

📄️ Diag

This function creates a diagonal matrix.

📄️ DiagIndx

DiagIndx returns the indices of elements along a diagonal of a square or rectangle matrix. The indices are returned a two dimensional array of integers.

📄️ DiagSize

DiagSize returns the size of the diagonal. It works for both rectangle and square arrays.

📄️ SetDiag

SetDiag routine can be used for setting the diagonal entries of a square dense matrix. The generic call is given below.

📄️ SetTriDiag

SetTriDiag routine can be used for setting the three diagonals (main, sub

📄️ TriDiag

Create a tridiagonal matrix.
