ginv: Get inverse
In PEIP: Geophysical Inverse Theory and Optimization
ginv R Documentation
Get inverse
Description
Get inverse of matrisx or solve Ax=b.
Usage
ginv(G, x, tol = 1e-12)
Arguments
G
Design Matrix
x
right hand side
tol
tolerance
Details
This function used as alternative to matlab code that does this h = G\x to get the inverse
Value
inverse as a N by 1 matrix.
Note
Be careful about the usage of tolerance

Examples
set.seed(2015)
GAB = matrix(runif(36), ncol=6)
truex =rnorm(ncol(GAB))
rhs = GAB %*% truex
rhs = as.vector(rhs )
tout = ginv(GAB, rhs, tol = 1e-12)
tout - truex
