function Y = erfi(x) %ERFI Imaginary error function. % Y = ERFI(x) computes the value of the imaginary error function % for the argument x. % % The imaginary error function is defined in terms of the error function % ERF via erfi(i*x) = -i*erf(-x). % See also erf, erfc, erfcinv, erfcx, erfinv % Copyright 2012 The MathWorks, Inc. Y = sym.useSymForNumeric(@erfi, x);
