Name

acotd — computes the element-wise inverse cotangeant of the argument result in degree.

Calling Sequence

y = acotd(x)

Parameters

x

Real or complex array.

y

Real or complex array.

Description

Computes the element-wise inverse cotangeant of the argument and returns the results in degree. For real argument w the result is real.

Examples

 
x=[1 2 -2 sqrt(2) -sqrt(2) 2/sqrt(3) -2/sqrt(3) -1];
acotd(x)
