So I'm trying to change my code from a for loop to while loop to display numbers from 10 to 30 and skips numbers from 15 to 20 and also 28. I did the for loop but however when i try to write it using a while loop i get an error.
This is for my for loop:
clear;
disp('This is the for loop version')
for k = 10:30
if (k > 15 && k < 20) || (k == 28)
continue
end
disp(k)
end
here is my while loop:
clear;
disp('This is the for while version')
k = 10;
while( k <= 30 )
if (k > 15 && k < 20) || (k == 28)
disp(k);
k = k + 1;
end
end
Also how do i stop the while loop from running? when i hit the run button it never stop running.
Thanks

Guillaume

Your question about the while loop has been answered. Note that the for loop version could be much simpler. Nothing is forcing you to pass a vector of continuous values to for, so:
for k = [10:15, 20:27, 29:30]
disp(k)
end
%that's it!

You need to move the statement
k=k+1
outside of the if block.
The first time you run the while loop, k has a value of 10, and the "if" test fails. K never gets updated.
k=10
while k<=30
if(k>15 && k<20) || k=28
dsp(k)
end
k=k+1
end
