Name

cosd — element-wise cosine function, argument in degree

Calling Sequence

y=cosd(x)

Parameters

x

real vector/matrix

Description

For a vector or a matrix x of angles given in degree, cosd(x) is the cosine of its elements. The results are in [-1 1]. For input elements which are equal to n*90 with n integer and odd, the result is exactly zero.

Examples


x=[0,30 45 60 90 360];
