ACOT Inverse Cotangent Function

Section: Mathematical Functions

# Usage

Computes the inverse cotangent of its argument. The general syntax for its use is

      y = acot(x)

where `x` is an `n`-dimensional array of numerical type.

# Internals

The `acot` function is computed from the formula

# Examples

Here is a simple plot of the inverse cotangent function

    --> x1 = -2*pi:pi/30:-0.1;
    --> x2 = 0.1:pi/30:2*pi;
    --> plot(x1,acot(x1),x2,acot(x2)); grid('on');
