Vector Multiply

It's been consolidated into the main Multiply component (which now works on vectors, numbers and complex numbers) - which I think this is much nicer than having separate components for all these.

The remaining Multiply now works on the following combinations:

Integer-Integer (should result in integer output)
Integer-Number
Number-Integer
Number-Number

Number-Vector (scale a vector)
Vector-Number (scale a vector)

Number-Point (multiply all the coordinates with the factor)
Point-Number (multiply all the coordinates with the factor)

Vector-Vector (dot product)

Complex-Complex (if you supply a complex number and a regular number it will revert to complex multiplication)

Colour-Colour (superimpose the colours, i.e. darken/stained glass effect)
Colour-Number (darken or lighten the colour based on the factor)
Number-Colour (darken or lighten the colour based on the factor)


The other operator components work in a similar fashion.

Thanks a lot all for the relies. So just as a confirmation

Vector X Vector is Dot product

and Vector + Vector  is Cross Product?

 

Many thanks in advance

Stephanie

Dot Product and Cross Product actually have their own components, but if you use the Multiply component with two vectors you do get the Dot Product as well.

Vector + Vector is just vector addition.
