Different utility functions to be used in rrcov and packages depending on rrcov

Description

Different utility functions to be used in rrcov and packages depending on rrcov:

• myscreeplot Plots screeplots for two covariance matrices

• mtxconfusion Computes a confusion matrix between actual and predicted class membership

• MATLAB-like functions

  • sqrtm Returns the square root of a symetric positive definite matrix

  • ones Returns a nxp matrix filled with ones

  • zeros Returns a nxp matrix filled with zeros
