Your information architecture diagram doesn't look quite right. For example, your [Females] should be a structure that holds heights and times, but you have it as an array of heights. I think you want something like this:
female_times = struct('Manual',manual_time,'Matlab',matlab_female);
Female = struct('Heights',female,'Times',female_times);
% ditto for males to make struct Male
SortedHeights=struct('Female',Female,'Male',Male)
FWIW, I would question using an information architecture like this in the first place. Why not, for example, just keep the times in a 2x2 array (gender, manual/matlab)?
