Question

I am trying to initialize a structure in MATLAB similar to how C code does

typedef struct{
 float x;
 float y;
} Data

Data datapts[100];

From MATLAB, I know this is how to create a structure:

Data = struct('x', 0, 'y', 0)

but how do you create 100 instances of it?

Or is this not usually done in MATLAB? Does MATLAB prefer dynamic allocation whenever there is new data to add?

Answer 1

repmat(Data,100,1);

You can assign data to it with:

Data(1).x = 10;
Data(1).y = 20;
