List comprehension-like function in assigning values in nested structures

Hi everyone,

I am coming from writing in Python and am very used to thinking in list comprehensions to form arrays/lists.

Specifically, in MATLAB I'd like to have a more comprehensive version of the following code, especially if the length of the data structure gets larger.

Suppose I have a data structure:

data(1).h = 5;
data(2).h = 4;

Now, I'd like to have all 'h' elements in one array like this:

h(1:2) = [data(1).h data(2).h]

As you see, I am now writing out the entire list, which will get very unwieldy when dealing with structures that go up to data(i) with i very large.

Does anyone have a suggestion how to do this "MATLAB-style", without using a for-loop?

Thanks in advance.

Try this:

h = [data.h];

You'll find the answer in this article on comma-separated lists, specifically with the deal() function. comma-separated lists
