rray (version 0.1.0)

rray_prod: Calculate the product along an axis

Description

rray_prod() computes the product along a given axis or axes. The dimensionality of x is retained in the result.

Usage

rray_prod(x, axes = NULL)

Arguments

x

A vector, matrix, or array to reduce.

axes

An integer vector specifying the axes to reduce over. 1 reduces the number of rows to 1, performing the reduction along the way. 2 does the same, but with the columns, and so on for higher dimensions. The default reduces along all axes.

Value

The result of the reduction as a double with the same shape as x, except along axes, which have been reduced to size 1.
