— Function File: cond (a,p)

Compute the p-norm condition number of a matrix. cond (a) is defined as norm (a, p) * norm (inv (a), p). By default p=2 is used which implies a (relatively slow) singular value decomposition. Other possible selections are p= 1, Inf, inf, 'Inf', 'fro' which are generally faster.
