LOG function

Description

Logarithm function. LOG(x) returns the logarithm of the positive number x to base 10. The argument x must be greater than 0.

The argument x can be a real number, a complex number, or a matrix. When it is a matrix, the function returns a matrix with the same dimensions and with the LOG function applied to all elements.

Example

LOG(100) equals 2
