asecd

computes the element-wise inverse secant of the argument, results in degree.

Syntax

y = asecd(x)

Arguments

x

Real or complex array

y

Real or complex array

Description

Computes the element-wise inverse secant of the argument, results in degree. For real input data with absolute value greater than 1 the results are real and in [-90 90].

asecd(x) is equal to asec(x)*180/%pi.

Sample

Examples

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