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         


        

Answer 1

According to this answer, there's also another way to do it:

[a.x] = deal(val);

where val is the value you want to assign to every element of the struct.

The effect of this command is different from those of the others, as every x field of every structure a will be assigned the val value.
