arrays and matrixes

can you make matrixes in spin· how do you assign an array or mattrix all at the same time without looping through the array

Mike Green

Spin has one dimensional arrays. You have to implement higher dimensions by yourself. For example, a 3 x 3 matrix is declared as an array of 9 elements. To access the i'th/j'th element, you'd use "i*3+j" as a subscript.

You'd have to loop through the array to do an assignment. There's no "syntactic sugar" for matrices.

yeah, thanks thats what i am doing now, just wondering if there was an easy way to initialize something.

Couldn't you use bytefill / wordfill to initialize the array? I read that it is much more efficient then looping through the array since the interpreter handles it internally.

For example, I use a 2d array by using the same method as Mike proposed. To init the array with all zeros, I do a bytefill(@buffarray, 0, BUFFLEN). BUFFLEN being the size of the array, and 0 being the value to fill with.
