order_B function

Reorder columns of a square matrix so that the first nonzero elements are in decreasing order

order_B takes a square matrix B as input and reorders its columns so that the diagonal entries of B are in decreasing order. The function is designed to be computationally efficient and ensures that the input is a square matrix.

order_B(B)

Arguments

• B: A square numeric matrix.

Returns

A square matrix B with columns reordered so that its diagonal entries are in a decreasing order.
