How to export field values from a struct to another struct in Matlab?

Question

I have a struct of 283 Area values and I want to copy the higher than 1000 values to a second struct with a for function. I have writen the code I need like this

Lbp = regionprops(Lblack, 'Area');
Lbp.Area;
[r,c]=size(Lbp);

B(r,c) = struct();


for d=1:r
    for g=1:c
          if Lbp(d).Area > 1000
              i=1;
              B(i)=Lbp(d);
              i=i+1;
          end
    end
end

I am getting this error Subscripted assignment between dissimilar structures. Even though the structs are the same size. I know that my syntax is wrong but I can not figure out how to syntax it in order to copy the fields to the second struct.

Answer 1

It's because B and Lbp do not have the same fields. Try the following:

B(r,c) = struct('Area',[]);
