The *matrix* one-norm is the largest column sum; the *matrix* infinity-norm is the largest

row sum. So mat_norm(matrix([1,2,3]),1) --> 3 and mat_norm(matrix([1,2,3]),'inf) --> 6 are

correct. You might be thinking that Maxima should convert matrix([1,2,3]) into the *vector*

[1,2,3]. Indeed, the one-norm of the *vector* [1,2,3] is 6 and the infinity norm of the

*vector* [1,2,3] is 3. But I think that such an automatic conversion is a bad idea. Maxima

should have a vector type, but it doesn't.

Unless somebody shows me that I'm mistaken, I'll mark this bug as invalid in a few days.

Thanks for the report.
