MATLAB: How to display the code line number

code linelineline number

Hello! Of all the questions people have asked, noone seem to have been wondering about this. Please correct/redirect me if I'm wrong!

Let's say I have a large amount of unique if-loops that are pretty much similar. Every if-loop has two options where the first is the actual script, and the other one is just a sort of else-prompt that only shows very rarely, or even never.

If I in the else-option want to use disp('This was not what you wanted') and after that tell me where in my code I actually am, like what code-line am I at, how could I do that?

If I get an error from, really whatever, it tells me what function file and what line number I'm at. This I want to be able to call myself. I know I can do it manually easily with something like disp('This was if-loop "Adam", and it wasn't right').

Thanks!

I suggest using the warning('msg'). It will tell you the code line number in the Command Window when it happens.

MATLAB: It is not working / it gives an error

Do you mean something like this:

 Dear God, I've tried it very hard, I'm due on Friday, but THE WORLD is
 not working yet. It always gives an error like "who cares" or "don't
 blame me", but the corresponding code lines are surely correct.
 Help me, it is urgent and more important that the problems of others.

Then God would either react as usual:

 Please post the code and add a complete copy of the error message

or as usual:

MATLAB: I keep getting a syntax error with the program??

in the If statement you need to use '==' Your first if statement would be

if x==0 & y==0 
 disp('This point is located at the origin.')

Your entire code

x=input('Enter value for x: '); 
y=input('Enter value for y: '); 
if x==0 & y==0 
    disp('This point is located at the origin.')
elseif x>0 & y==0 
    disp('This point is located on the x-axis.') 
elseif x==0 & y>0 
    disp('This point is located on the y-axis.') 
elseif x>0 & y>0 
    disp('This point is located in the first quadrant.') 
elseif x<0 & y>0 
    disp('This point is located in the second quadrant.') 
elseif x<0 & y<0 
    disp('This point is located in the third quadrant.') 
elseif x>0 & y<0 
    disp('This point is located in the fourth quadrant.') 
end
