Inverse of matrix in R

Question

I was wondering what is your recommended way to compute the inverse of a matrix?

The ways I found seem not satisfactory. For example,

> c=rbind(c(1,          


        

Answer 1

solve(c) does give the correct inverse. The issue with your code is that you are using the wrong operator for matrix multiplication. You should use solve(c) %*% c to invoke matrix multiplication in R.

R performs element by element multiplication when you invoke solve(c) * c.
