How to Create a Column Vector of a Field of a Struct?

How to create column vectors out of B (i.e., D = [10;20;30]) and C (i.e., E = [100;200;300])?

A(1).B = 10;
A(2).B = 20;
A(3).B = 30;
A(1).C = 100;
A(2).C = 200;
A(3).C = 300;

[Jan]

D = [A.B];
E = [A.C];

This is the short for of:

[A(:).B]

which has the advantage, that the intention is more obvious during reading.

Splendid! Thanks!

This syntax is explained in the documentation:

https://www.mathworks.com/help/matlab/matlab_prog/comma-separated-lists.html

PS: the question asks for a column vector, and the answer above gives a row vector. Either transpose, or use vertcat:

 D = vertcat(A.B);
