acotd

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

Calling Sequence

y = acotd(x)

Arguments

: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 x the result is real.

Sample

Examples

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