gmatrix-class: Class "gmatrix"

In gmatrix: GPU Computing in R

Description

This object contains a pointer to a matrix on a NVIDIA GPU.

Objects from the Class

Objects should NOT be created by calls of the form new("gmatrix", ...). Instead use the gmatrix, 'as.gmatrix' or 'g' functions.

Slots

ptr:

Represents an external pointer to the data on the GPU

nrow:

Object of class "integer" representing the number of rows for the matrix

ncol:

Object of class "integer" representing the number of cols for the matrix

rownames:

Should be a character vector with length equal nrow

colnames:

Should be a character vector with length equal nrow

type:

Must be 0L, 1L, 2L or 3L. These integers represent the types "double", "single", "integer" or "logical" respectively.

device:

Object of class "integer" representing the device
