Cody, Argonne National Laboratory, NETLIB/SPECFUN, March 19, 1990. Why do central European nations use the color black as their national colors? Remarks The relationship between the complementary error function erfc and the standard normal probability distribution returned by the Statistics Toolbox function normcdf is The relationship between the inverse complementary error Compute the inverse error function for elements of matrix M and vector V:M = sym([0 1 + i; 1/3 1]); V = sym([-1; inf]); erfinv(M) erfinv(V)ans = [ 0, erfinv(1 + https://www.mathworks.com/help/matlab/ref/erfinv.html

The function erfinv satisfies for and . Instead, **replace erfinv(1-x) with erfcinv(x).** For more information, see Tall Arrays.TipsFor expressions of the form erfinv(1-x), use the complementary inverse error function erfcinv instead. The resulting code is about three times faster in execution, but is considerably less accurate.
