Comments
If expr is a scalar, the result is a scalar which is the trigonometric cosine of expr.
If expr is a vector, the result is a vector of the same dimensions containing a trigonometric cosine for each element of expr.
If expr is a matrix, the result is a matrix of the same dimensions containing a trigonometric cosine for each element of expr.
