Hi, i want to sum each 3 columns of my array for any array dimension.
For example, Y array is the sum of each X array respectively to its color.
Need this to do sum for Nx150 array, so that it can turn into Nx50 array
Thanks!

reshape(x, size(x,1), 3, [])
now you can sum along the second dimension, and then reshape to remove the now-singular second dimension.
