problem finding the coordinates of point in stainer tree problem by brute force

hi

what's wrong with the coding. i want to find the value of 'a' and 'b' for which 'L' is minimum.

>> [m,a,b]=min_length(10:.01:40,5:.01:25)

m =45.7813

a = 40

b = 25

these are not the correct value of 'a' and 'b'.

thank you.

your if is ending 3 lines to early. No matter what happens, you get a = x(end) and b = y(end). the m you get is the last that fullfilled the relation L<M.
