MATLAB: Combine values from struct.

Question

I have a struct of 1×30 and every struct have a large double every one different but same number of columns.

I want the values from all the doubles to form one matrix. How can I do that?

Answer 1

See vertcat(). Run this example

s1(1).a = [1 2 3];
s1(2).a = [4 5 6; 7 8 9];
s1(3).a = [1 2 3; 4 5 6; 7 8 9];
vertcat(s1.a)

Result

ans =
     1     2     3
     4     5     6
     7     8     9
     1     2     3
     4     5     6
     7     8     9
