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?

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"?

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.

perhaps you're looking for break or return
doc break
doc return
?
