p_ginv_sq: Power generalized inverse of a symetric matrix

Description

Calcualte the pwoer generated inverse of a symetric matrix by using eigen dicompostion.

Usage

p_ginv_sq(X, p)

Arguments

X

X is the data input matrix and it should be symetrix.

p

p is the power. For example, to calculate the inverse of X, p is set to be 1.

Value

The power inverse of the input matrix.

Details

p_ginv is use to calcuate X^(-p).
