: cosd (x) ¶ Compute the cosine for each element of x in degrees. The function is more accurate than cos for large values of x and for multiples of 90 degrees (x = 90 + 180*n with n an integer) where cosd returns 0 rather than a small value on the order of eps. See also: acosd, cos. : tand (x) ¶ Compute the tangent for each element of x in ...Description example Y = acosd (X) returns the inverse cosine (cos -1) of the elements of X in degrees. The function accepts both real and complex inputs. For real values of X in the interval [-1, 1], acosd (X) returns values in the interval [0, 180].

Description. C = A.*B multiplies arrays A and B by multiplying corresponding elements. The sizes of A and B must be the same or be compatible. If the sizes of A and B are compatible, then the two arrays implicitly expand to match each other. For example, if one of A or B is a scalar, then the scalar is combined with each element of the other array.Link. Edited: MathWorks Support Team on 27 May 2020.
