cosd

Cosine of argument in degrees

Syntax

Description

example

Y = cosd(X) returns the cosine of the elements of X, which are expressed in degrees.

Examples

collapse all

cosd(90)
ans =

     0

cos(pi/2)
ans =

   6.1232e-17

Create an array of three complex angles and compute the cosine.

z = [180+i 45+2i 10+3i];
y = cosd(z)
y =

  -1.0002 + 0.0000i   0.7075 - 0.0247i   0.9862 - 0.0091i

Input Arguments

collapse all

Angle in degrees, specified as a real-valued or complex-valued scalar, vector, matrix, or N-D array. The cosd operation is element-wise when X is nonscalar.

Data Types: single | double
Complex Number Support: Yes

Output Arguments

collapse all

Cosine of angle, returned as a real-valued or complex-valued scalar, vector, matrix, or N-D array of the same size as X.
