%CSCD Cosecant of argument in degrees. % CSCD(X) is the cosecant of the elements of X, expressed in degrees. % For integers n, cscd(n*180) is infinite, whereas csc(n*pi) is large % but finite, reflecting the accuracy of the floating point value for pi. % % Class support for input X: % float: double, single % % See also ACSCD, CSC. % Copyright 1984-2010 The MathWorks, Inc. % Built-in function.
