mot566_log

Perform a natural logarithm.

MATLAB Syntax

Y=mot566_log(X)

Description

mot566_log(X) returns the natural logarithm value of vector or matrix X. Complex results are produced if X is either negative or complex.

Characteristics

In the workspace, if the input is:

X=[0.4807 + 0.0000i   0.8319 - 0.2921i
   0.0000 + 0.6717i   0.5273 + 0.7144i]

the returned value is:

mot566_log(X)
ans=-0.7325            -0.1259 - 0.3377i
    -0.3979 + 1.5708i  -0.1189 + 0.9350i

Arguments
X
Vector (or matrix) with elements normalized in the range [-1,1] (for complex elements, both real and imaginary parts should comply with this limit).

Y
Natural logarithm of input.
