condnb_erfcond — Computes the condition number of the erf function.
[c,y] = condnb_erfcond ( x )
a n-by-m matrix of doubles
a n-by-m matrix of doubles, the condition number
a n-by-m, matrix of doubles, the function values
Computes the condition number of the erf function. The erf function is always well conditionned, since its condition number is never greater than 1.
