MatMult: MatMult: Specialized matrix multiplication of 'DMat',...

In HiDimDA: High Dimensional Discriminant Analysis

Description

‘LeftMult’ multiplies, on the left, a vector or matrix of compatible dimensions, by a ‘DMat’, ‘ShrnkMat’, ‘ShrnkMatInv’, ‘SigFq’ or ‘SigFqInv’ object.

‘RightMult’ multiplies, on the right, a vector or matrix of compatible dimensions, by a ‘DMat’, ‘ShrnkMat’, ‘ShrnkMatInv’, ‘SigFq’ or ‘SigFqInv’ object.

Usage

## S3 method for class 'DMat'
LeftMult(x, a)

Arguments

x	An object of class ‘DMat’, ‘ShrnkMat’, ‘ShrnkMatInv’, ‘SigFq’ or class ‘SigFqInv’, with a compact representation of a specialized square symmetric matrix.
a	A vector, or matrix, by which ‘x’ is to be multiplied.

Value
