WebJan 10, 2014 · Divide your identity matrix along the columns. If you have p CPUs and your matrix is n-by-n, then every part has n/p columns and n rows. Lets call the parts I1, I2, etc. On every CPU, solve a system of the form A*B1 = I1, this gives you the parts B1, B2, etc., and you can combine them to form B which is the inverse. Share. WebSep 17, 2024 · Definition 3.1.1. An n × n matrix A is called invertible if there is a matrix B such that BA = In, where In is the n × n identity matrix. The matrix B is called the inverse of A and denoted A − 1. since A rotates vectors in R2 by 90 ∘ and B rotates vectors by − 90 ∘. It's easy to check that.
