%TAND Tangent of argument in degrees. % TAND(X) is the tangent of the elements of X, expressed in degrees. % For odd integers n, tand(n*90) is infinite, whereas tan(n*pi/2) is large % but finite, reflecting the accuracy of the floating point value of pi. % % Class support for input X: % float: double, single % % See also ATAND, ATAN2D, TAN. % Copyright 1984-2011 The MathWorks, Inc. % Built-in function.
