Assign elements in multidimensional struct to 2D array

I have a 1xN multidimenstional struct, where each entry contains data of size 1xM.

for ii=1:5, C(ii).pts = rand(1,3); end

I would like an elegant way to get an NxM array as a concatinated output of the struct. Is this possible?

% Returns of size 1xMN 
[C.pts]

% Will not run but get something like this of size NxM
[c.pts']

You are not limited to only using square brackets for concatenation, you can use a comma-separated list with any operator or function that accepts those input arrays:

cat(1,C.pts)
vertcat(C.pts)

This was exactly what I was looking for, thank you

You can use the vercat( ) function to force the comma-separated-list generated by C.pts to stack vertically:

for ii=1:5, C(ii).pts = rand(1,3); end
vertcat(C.pts)
