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];
