I have a structure which contains two fields one of them contains vectors,example:
myStruct(1).f1 = val1;
myStruct(1).f2 = [elt1 elt2 elt3];
I want to find the indices of the elements of myStruct where elt1 == valA and elt2 == valB

One way to do this would be:
% Create a matrix whose rows are the f2 vectors in the struct array
A = cell2mat({myStruct.f2}.');
% Find which rows match your conditions
Matches = (A(:,1) == valA) & (A(:,2) == valB);
% (If required: convert logical vector to indices)
Indices = find(Matches);

Thank you! it works without even converting the logical vector to indices
Another way to do this:
F2 = reshape([myStruct.f2],3,[]);
Indices = find(((F2(1,:) == valA) & (F2(2,:) == valB)));
