cos#
Purpose#
Returns the cosine of its argument.
Format#
- y = cos(x)#
- Parameters:
x (NxK matrix) – data, for real matrices should contain angles measured in radians. To convert degrees to radians, multiply the degrees by
.- Returns:
y (NxK matrix) – containing the cosines of the elements of x.
Examples#
// Create a sequence starting at 0 and increasing by pi/4
x = seqa(0, pi/4, 5);
y = cos(x);
