To put it simple my code similar to :
k=6 if(a/b<k) && (a/b>=0) STATEMENT1 elseif(a/b>-k) && (a/b<0) STATEMENT2 end
The problem is i got a/b = 0, so it should give me STATEMENT1 but i got STATEMENT 2, does anyone know how i can figure out my mistake?
No products are associated with this question.
Try using the command
format long g
and then displaying a/b
It probably isn't really 0.
Please read your question again and note, that Matlab does not perform any strange or magic actions. Then these two details:
1. if(a/b<k) && (a/b>=0) 2. The problem is i got a/b = 0, so it should give me STATEMENT1 but i got STATEMENT 2
imply, that either a/b<k is FALSE, or your assumption that a/b==0 is wrong. A third possibility is, that you did not save the M-file after editing, such that Matlab does not run the program you currently see in the editor.
There are no other solutions. Walter's suggestion to increase the displayed precision is exhaustive to identify the problems.
