Truncate any of the variables that contain more than the number of points in the shortest test-run (I.e. the smallest value of N)

Ask them.

They may want all the arrays to be (2x23) arrays.

Use size() or numel() to find the existing lengths. Find the minimum of them. Use indexing like A(1:HOWLONG) to pull out part of the array.
