pseudoinverse R Documentation
Find the Pseudoinverse of a Matrix
Description
Find the Pseudoinverse of a Matrix
Usage
pseudoinverse(X)
Arguments
X
A numeric matrix.
Details
The pseudoinverse of a matrix is V Σ^+ U^T - essentially, its inverse over its row space. It always exists even if no left or right inverse does.
This function is partly based on the ginv, which does the same thing.
Value
The pseudoinverse of X.
Examples
pseudoinverse(matrix(rnorm(12), ncol = 3))
