In kaneplusplus/bigalgebra: BLAS Routines for Native R Matrices and 'big.matrix' objects

Description

This function implements the function Y := ALPHA + Y where Y may be either native double-precision valued R matrices or numeric vectors, or double-precision valued big.matrix objects, and ALPHA is a scalar.

Usage

dadd(Y, ALPHA, SIGN=1, ALPHA_LHS=1)

Arguments

Y	Requried to be either a native R matrix or numeric vector, or a big.matrix object
ALPHA	Required to be a scaler.
SIGN	1 for addition -1 for subtraction.
ALPHA_LHS	Should SIGN be multiplied by Y (default) or alpha.
