In your case, the first linearly independant are the 3 first columns. import sympy import numpy as np matrix_a = np.array ( [ [-3, 1, 4, 0, 0], [1, 0, -1, 1, 0], [1, 0, 1, 0, 1]]) echelon, index = sympy.Matrix (matrix_a).rref () WebSo now we have a condition for something to be one-to-one. Something is going to be one-to-one if and only if, the rank of your matrix is equal to n. And you can go both ways. If you assume something is one-to-one, then that means that it's null space here has to only have the 0 vector, so it only has one solution.
