How to initialize an array of structs in MATLAB?

Question

How can I preallocate an array of structs in MATLAB? I want to preallocate \"a\" in this example so that it does not resize several times.

a = []
for i = 1:1

There's a nice discussion about this in Loren on the Art of MATLAB blog.

If I understand you correctly, here's a ways to initialize the struct you want:

a(100).x = 100;

With this method, we can see that elements are filled in with empty arrays.
