Sort multidimensional array along one dimension

I have a [80 80 3 646 2] sized array of measurements which represent [80 80 3] points each with its 646 values at [: : : : 1] and time of measurement at [: : : : 2]. Now I want to order this 5 dimensional array along the values of time of measurement (so I can more easily interpolate/downsample later, but the first step I cant figure out is ordering).

I tried the sort function on the last dimension, but that did not sort it along the time values.

If you want to sort along the fifth dimension, use:

xsorted = sort(x,5);

The second value of the fifth dimension has all timepoints, I want to sort to that. The first value of the fifth dimension however has all the values, so I think thats why sort(x, 5) did not work. As I said above I already tried sorting it on the last dimension. I think I need something inbetween sortrows and sort.

It sounds to me like you really have two separate arrays: a 4d array for measurement and a 4d array for time. If you create these, you can sort them how you wish (use the second output from sort to do the ordering in both if necessary).

Ah terrific, this works
