Parameters

array:float[]: The array to split up into blocks.
blockSize:int: The size of the blocks to split the array into. This must be an exact divisor of the length of the array, or some data will be lost from the main array.

Returns:float[][]

offs:int: The offset in the array that corresponds to the first index of the subarray.
len:int: The number of indeces in the subarray.

Returns:float[]

The subarray, which may be of length 0.
