Can anyone help me?

I'm having trouble finding information about this. I *want* someone to walk me through a simple tensor calculation. From what I read an inner product is a tensor, as is a matrix, however how would you place 3 pieces of related information in a tensor?

I think first you need to learn how to post your question in the relevent forum instead of spamming the general forum.

I've bugged Dave for a maths forum but he doesn't seem to like it, nor do any of the other members. Basically my issue:
I'm doing this: Mv = c
----------
[a, b, c][point0] = [affineScaledSum1]
[d, e, f][point1] = [affineScaledSum2]
[g, h, i][point2] = [affineScaledSum3]

Question is, if I am doing dot products between points, how would I go about storing and doing this operation through tensors?

There's coding sections on this forum that you simply can not find your way into. That's your problem.

See? When he writes stuff like that I just keep thinking he's GOT to have a halfway decent processor in his head!

This isn't coding. It's maths. Tensors = maths.

This isn't coding. It's maths. Tensors = maths.

You're still MUCH more likely to get help in one of the coding areas than here.

Sorry. Let me re-phrase my entire thread:

Affine sums are additions of points scaled by a scalar.

The dot product in my matrix is the multiplication of the matrix elements by a point in the vector, however the vector is a literal vector and not a matrix.

[x,y] * [a b c] = (x*a, y*a) + (x*b, y*b) + (x*c, y*c)
= (x(a+b+c), y(a+b+c))

The thing is, this should be done using tensors.
