I have written a code as below:
a=5:-1:-2;
i=1;
while(1)
if(a(i)<0)
break;
end
b=a(i)*2;
i=i+1;
if(b>=4)
continue;
end
disp('b<4')
end
disp('end of computation')
The script includes continue and break statements. Note that break will exit the innermost enclosing of while or for loop; while continue will jump to the end of the innermost enclosing while or for loop.
I wish to rewrite my code by removing break and continue so that it looks nicer. Any suggestions? Thank you.

You can remove the if statement containing the break by just using the opposte condition as the conditional statement controlling the while loop execution.
while a(i)>=0
You could reverse the contitional on your 2nd if statement, and replace continue with your disp command.

Not sure what you are trying to do, but the final b is going to be zero.
a=5:-1:-2;
b=0;
disp('b<41');
disp('b<41');
disp('end of computation');
