Log: Natural Logarithm each element of a matrix

In Rfast: A Collection of Efficient and Extremely Fast R Functions

Natural Logarithm each element of a matrix

Description

Natural Logarithm each element of a matrix.

Usage

Log(x, na.rm = FALSE)

Arguments

x	A matrix with data.
na.rm	A boolean value (TRUE/FALSE) for removing NA.

Details

The argument must be a matrix. For vector the time was the same as R's "log" function so we did not add it.

Value

A matrix where each element is the natural logarithm of the given argument.
