Let's say there are 2 structure arrays, A and B.
A is a 300x1 size structure, and B (112x1) is a subset of A, which means B is randomly selected from A.
I want to remove those rows from A so that the size of A becomes 118x1.
How can I deal with this problem??

How did you randomly select B? Do you have indexes or a logical vector? The obvious thing to do would be to take the complement of that selection from A.

A = rand(300,1) ;
idx = randperm(300,112) ;
B = A(idx) ;
val = ismember(A,B) ;
iwant = A(~val) ;
