Question

Write a function that takes an array A and reduces it to row echelon form, returning the modified array A. To do this, iterate over each row. Find the first non-zero column. Perform row operations so that (a) this first non-zero entry is set to one, and (b) all entries in this column but in rows with larger index are set to zero.

Answer 1

import scipy
import numpy as np
def row_ech(list1):
    return scipy.linalg(np.array(list1))
