Comapring Values in one Matrix to another

I have two matrixes

A = [373 383 393 403 413 420 451 485 499] ; B = [373 453 457 461 464]

I want two compare each value of A to every value of B and create a new matrix which is a collection of all the values of A which are bigger than at least one value in B

For example, I want to compare 383 from A to every value in B, and since its bigger than 373 in B I want to store it in a new matrix say called C.

I want to do this for every element in A

How can I do this?

Any help appreciated.

The simple MATLAB way:

>> A = [373,383,393,403,413,420,451,485,499];
>> B = [373,453,457,461,464];
>> C = A(A>min(B))
C =
   383   393   403   413   420   451   485   499

Neat!

What about:

A = [373 383 393 403 413 420 451 485 499] ; B = [373 453 457 461 464];
k = 1;
for i = 1:length(A)
    t = A(i);
    if any(t>B)
       C(k) = t;
       k = k+1;
    end
end

Another approach:

A = [373 383 393 403 413 420 451 485 499]; 
B = [373 453 457 461 464];

C = ones(numel(B),1)*A;                             % Expand ‘A’
C = C.' .* (A(:)>B);                                % Multiply By Logical Array
C = unique(C);                                      % Create Vector Of Unique Values
