Retrieving data from a structure

Hi,

I have a 1x36 structure with 34 fields called Dat_store. The first field contains 36 times a 1x4 vector with information on com: K4_com. Now I'd like to extract this CoM data and create a 36x4 matrix one value of the 1x4 vector in each column of the matrix. I tried

K4_COM = [Dat_store_12().K4_com];

But that gives me a 1x144 vector, which is not what I want.

Does anybody know what the correct command should be?

Thanks

[Guillaume]

K4_COM = vertcat(Dat_store_12.K4_com)

is the correct syntax (yours was equivalent to horzcat(Dat_store_12.K4_com) hence why they were all concatenated in a row).

K4_COM = [Dat_store_12().K4_com];
iwant = reshape(K4_COM,4,[])' ;
