I'd like to include the test case listed below, but I'm stumped as to why it doesn't work:
%%
x1 = [ 1 2 3 ]
x2 = [ 10 20 ]
y_correct = [9 19; 8 18; 7 17]
y_actual = gridit(@minus, x1, x2);
assert(isequal(y_actual, y_correct));
Alex, I believe it is because the 'minus' function requires two input arguments. The test cases and the example use functions that accept a single input argument. Hope that helps.
