assert_expcond — Computes the condition number of the exp function.
[c,y] = assert_expcond ( 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 exp function. The exp function grows so fast that it is equal to %inf whenever x > 800, and is equal to 0 whenever x < -800. This function has a not so bad condition number, since it is never larger than 1.e2.
