Name
cosd — element-wise cosine function, argument in degree
Calling Sequence
y=cosd(x)
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];
