WebInverse of a Matrix. We write A-1 instead of 1 A because we don't divide by a matrix! And there are other similarities: When we multiply a number by its reciprocal we get 1: 8 × 1 8 = 1. When we multiply a matrix by its inverse we get the Identity Matrix (which is like "1" for matrices): A × A -1 = I. Web14 apr. 2014 · Equality of Two Vectors. Create two vectors containing both real and imaginary numbers, then compare the vectors for equality. A = [1+i 3 2 4+i]; B = [1 3+i 2 4+i]; A == B. ans = 1x4 logical array 0 0 1 1. The eq function tests both real and imaginary parts for equality, and returns logical 1 ( true) only where both parts are equal.
