  • Hello!

    Is there some way to do array math operations like rotating, summing, subtract etc... ?

    I need to rotate an Array (yes, the values in the matrix) and sometimes sum this array in another array.

    Any info/tutorial on this?

    Thanks

  • Rotation should be easy enough:

    Array2 set size to (Array.Height, Array.Width)

    For x=0 to Array.Width-1

    ...For y=0 to Array.Height-1 -> Array2 set at X:loopindex("y"), Y:loopindex("x"), value:Array1.At(loopindex("x"), loopindex("y"))

    Can I use it to rotate clockwise or counter-clockwise? (I need to do both).

  • No... That's the same as "transpose" feature in Excel:

    For clockwise rotation try this:

    For x=0 to Array1.Width-1

    ...For y=0 to Array1.Height-1 -> Array2 set at

    ............X:loopindex("y")

    ............Y:((Array1.width-1)-loopindex("x")

    ............value:Array1.At(loopindex("x"), loopindex("y"))

    (This is just off the top of my head, not sure if it's correct)
