I feel embarassed to answer my own question only a short while after giving it some though, but the solution is quite simple really. THe outer loop iterates over the dimension, the inner loop over the size of that dimension. There are about ~1000 elements in each array although each array is a different length from each other. i'm guessing i need to nest it somehow but i have no idea, a few clues on where i'm wrong would be great, "i'm guessing i need to nest it somehow but i have no idea, a few clues on where i'm wrong would be great", https://www.mathworks.com/help/matlab/getting-started-with-matlab.html, https://www.mathworks.com/help/matlab/matlab_prog/vectorization.html.
