MATLAB: Changing variable after each loop iteration

homeworkinputvariablewhile loop

Will it be possible to change the variable or assign an new variable after each loop iteration

a=9
while a>0
  a=input('Example')
end

I don't want to collect it in an array.

Thank you

In my opinion that's ridiculous. Collect it in an array - the whole rest of the world does it, so why can't you? Anyway, your code does change the variable value, just not its name.

MATLAB: Only clear the variables in for loop

It is rarely useful to clear variables in the workspace. In many cases this decreases the speed. Prefer a proper pre-allocation, such that clearing is not required anymore.

30 Variables are a lot for a loop. Remember that a high code complexity reduces the readability and maintainability. The need to clear variables might be a secure signal, that the complexity has grown over a certain limit. A solution would be to move the body of the loop into an extra function. Then the smaller piece of code is easier to test, to modify, to debug and to maintain, and in addition the workspace is kept clean automatically.
