What the shit are you talking about?

Consider the following:
Kill you are self

consider the following:

Which language?

Don't use arrays. They're the devil's handy work.

what language?java? learn how to use collection classes instead of arrays

I can hook you up for php and javascript arrays.

>>51528529
JS array only has integeres as index.

['val0','val1','val2','val3']

JS object can be used instead of an array and the index can also be a string.

{'0':'val0','1':'val1','2':'val2','3':'val3'}

What's the issue?

An array is just a special case of a matrix.

Think about matrices, and follow the rules of matrices instead those of numbers and you'll be fine.
(i.e., unlike numbers, not every matrix in invertible, commutativity generally doesn't apply, not all matrices can be multiplied together, there are divisors of zero, etc.).

What exactly are you having difficulty with?

Don't waste your time, dude. The OP has never done matrix operations, I'm sure.

Even then I usually just use NumPy for matrix computations and barely have to think about it.

i don't see the problem.
