Structure initialization with repmat

Question

I want to initalize structures and it seems to be too slow. How do I do it with repmat, which is supposed to be a much faster solution in Matla

Answer 1

Well in this case the first question is why are you using a cell array of structs. One of the fundamentals of matlab is that everything can be vectorised. So instead set up a matrix of structs.

% Define the empty struct, struct itself is vectorised   
myloc=struct('s',cell(10,30),'f',cell(10,30));
%Assign values
[myloc(:).s]=deal(0),[myloc(:).f]=deal(0);

A matrix of structures is a far more powerful datatype. For example if you want to extract a single row of the field in to a vector you can simply use the following syntax

sRow8=[myloc(8,:).s]
