condnb_erfinvcond

Computes the condition number of the erfinv function.

Calling Sequence

[c,y] = condnb_erfinvcond ( x )

Parameters

x :

a n-by-m matrix of doubles

c :

a n-by-m matrix of doubles, the condition number

y :

a n-by-m, matrix of doubles, the function values

Description

Computes the condition number of the erfinv function. The erfinv function has a large condition number if

where

Examples

[c,y] = condnb_erfinvcond ( 0 ) // 1
[c,y] = condnb_erfinvcond ( 0.5 )
[c,y] = condnb_erfinvcond ( 1.e2 )

condnb_plotcond ( condnb_erfinvcond , linspace(-1,1,1000) );
