assert_acoscond — Computes the condition number of the acos function.
[c,y] = assert_acoscond ( 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 acos function. The acos function has a large condition number if
<latex> \begin{eqnarray} c(x) = \left| \frac{x}{\sqrt{1-x^2}\arccos(x)} \right| \end{eqnarray} </latex>
