Compare values within a matrix

I am comparing two matrices of different dimensions (A and B). I want to find values in B that are within 1 number unit to A. Is there anyway I can do this? B is a smaller matrix than A.

Thanks

What does that mean?

Answer 1

if you mean to find all numbers that are equal to each other when disregarding the numbers behind the comma than you can use something like this

A_r = round(A);
B_r = round(B);
C = intersect(A_r,B_r);

Hi Thanks but I want C to be a matrix of values that are within 1 unit of A, from B.

For example:

A = [31 16 8; 38 4 10]

B = [30 15 7; 34 5 14]

C would index that row 1 of A is a match to row 1 of B, because B is within +/- 1 of A

Is that possible?

A = [31 16 8; 38 4 10];
B = [30 15 7; 34 5 14];

nA = size(A, 1);
match = false(1, nA)
for iA = 1:nA
  D         = abs(bsxfun(@minus, A(iA, :), B)) <= 1.0;
  match(iA) = any(all(D, 2));
end
