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!

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.

S = load('Combined_Structure.mat','ModOutRstance_interp_x_all');
new_struct = struct();
f = fieldnames(S.ModOutRstance_interp_x_all);
for ii = 1:numel(f)
new_struct.(f{ii}) = vertcat(S.ModOutRstance_interp_x_all.(f{ii}));
end
disp(new_struct);

s(1).f=1:3;
s(2).f=4:6;
s(3).f=7:9
s = 1×3 struct array with fields:
f
vertcat(s.f)
ans = 3×3
1 2 3 4 5 6 7 8 9

How about this:
s = load('Combined_Structure.mat');
Warning: Could not find appropriate function on path loading function handle C:\Users\jtome\Box\Haddas' Lab\Code\Gait\NexusIntegrationRstanceOnly.m>@(f)interp1(f.',linspace(1,size(f,2),101)).'
Warning: Variable 'vicon' originally saved as a ViconNexus cannot be instantiated as an object and will be read in as a uint32.
m = s.ModOutRstance_interp_x_all;
allm = vertcat(m.LHipAngles)
allm = 3×101
