WebI need to compute AB⁻¹ in Python / Numpy for two matrices A and B (B being square, of course).. I know that np.linalg.inv() would allow me to compute B⁻¹, which I can then multiply with A.I also know that B⁻¹A is actually better computed with np.linalg.solve().. Inspired by that, I decided to rewrite AB⁻¹ in terms of np.linalg.solve().I got to a formula, based on the … WebThe definition of inverse is a*a-1 = I (ie a operated with inverse should give identity element) a-1*a = I (ie a inverse operated with a should also give identity element) so here.
