if/for loop problem

so i have this code:

    increments=input('Give in the increments between lines in degrees F:  ')
    disp('F.degrees  kelvin')
    for i= increments:32:212.0
        for z= 0:1:36
            z=32+increments*z; 
        x=z;
        y=5*(x-32)/9+273.15;
        if x==212
            ......????
        end
        fprintf('\n %2.2f    %2.2f',x,y);
        end
    end

but i cant seem to make it work I want the table to stop working when the value of x=212, and im not sure how to stop the loops

any ideas?

so i put in a doc break

increments=input('Give in the increments between lines in degrees F:  ')
disp('F.degrees  kelvin')
for i= increments:32:212.0
    for z= 0:1:36
        z=32+increments*z; 
    x=z;
    y=5*(x-32)/9+273.15;
    if x==212
          doc break;
      end
         fprintf('\n %2.2f    %2.2f',x,y);
      end
  end

however i get

"Overloaded functions or methods (ones with the same name in other directories) doc simulink/break"

"doc break" is for you to type in Command Window so you can learn about the usage of break(). The actual code you put in place is just break. BTW, you probably should put your condition as x>=212, instead of x==212. Just my guess. Also, look into your variable z. Why is it used for loop index and then over-written in the code?

Answer 1

[Fangjun Jiang]

Your inner loop has problem. The variable z is over-written. Probably you meant "for k=0:1:36", instead of "for z=0:1:36"?

replacing k with z doesnt seem to work either, i get an output of

??? Undefined function or variable 'z'.

Error in ==> Untitled at 5

z=32+increments*z;

[Fangjun Jiang]

You need to know what you are trying to do. I just found an obvious mistake. You are try to do a loop using z as index from 0 to 36 and then you are over-write the variable z!!!

If you are using k as the index, then probably should be z=32+increments*k.

ohh i see it now

Answer 2

[Sean de Wolski]

perhaps you're looking for break or return

doc break
doc return

?
