## 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.
