Combining rows of each field within a structure

Hello,
I'd like to combined the rows of a structure for each field. I won't always know how many rows there will be in the structure. The example I show is a 1 x 3 structure, but I'd like to plan for a 1 x ? structure. So I thought combining the rows in a for loop would be the best way. I'm aiming for a 3 x 101 double in each of the fields in this example.
I'm sure there's a pretty easy solution to this but I'm a novice when it comes to MATLAB
Any help would be greatly appreciated!

You forgot to attach your variable in a .mat file. Perhaps try vertcat.
If you have any more questions, then attach your data and code to read it in with the paperclip icon after you read this:

Here is my .mat file. I am importing my data directly from another software program that works directly with MATLAB. As you can see from above the structure I'm working with is name "ModOutRstance_interp_x_all" (I know that's a long name). I've also attached the code I have up to this point.

How about this:
s = load('Combined_Structure.mat');

m = s.ModOutRstance_interp_x_all;
allm = vertcat(m.LHipAngles)
