matrix.concatenate

R Documentation

Creates a concatenation of the matrices.

Description

Creates a concatenation of the matrices.

Usage

matrix.concatenate(mats, axis = 2, n_threads = 1)

Arguments

`mats`	List of matrices.
`axis`	The axis along which the matrices will be joined. With axis = 2 (default) this function is equivalent to `cbind()` and axis = 1 is equivalent to `rbind()`.
`n_threads`	Number of threads.

Value

Concatenation of matrices. The object is an S4 class with methods for efficient computation in C++ by adelie. Note that for the object itself axis is represented with base 0 (so 1 less than the argument here).

n <- 100
ps <- c(10, 20, 30)
ps <- c(10, 20, 30)
n <- 100
mats <- lapply(ps, function(p) {
    matrix.dense(matrix(rnorm(n * p), n, p))
})
out <- matrix.concatenate(mats, axis=2)
