Test numeric.solveLP()

2

Test numeric.solveLP() against standard test problems. Right now, it's only tested against randomly generated L1 norm minimization problems.

Typed array matrices

9

How is a typed array matrix specified? Is it an Array of typed Arrays? Or is it a single flat typed array? Is it reasonable to take a flat Float64Array...

Integrator does not allow for backward propagation (x1 < x0)

Fill-reducing accelerates the factorization a lot. It is essential.

Bug in numeric.eig()

1

numeric.eig() on the identity returns funny results. This is because the handling of multiple eigenvalues is sort of weird right now. This is a bug and it should be fixed.

`numeric.transpose([[]])` results in `[]` instead of `[[]]` like it should.

Automatic differentiation

2

Should this be implemented using an AD object? Can this AD object handle linear algebra? How much of it is orthogonal to numeric?

Bug in 'numeric.inv()'

4

Computing "numeric.inv([[8,9,8,9], [5,6,5,6], [8,9,8,9], [5,6,5,6]]);" results in an error: "TypeError: Aj is undefined"

Add numeric.toMathml() method

4

Have you considered adding a method like numeric.prettyPrint(), but to output numbers, vectors and matrices (including sparse matrices) in mathml? I think this would be nice for working in Workshop....
