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

This would a question collecting input for gears 1,2,3,4,5,6,7...... in the loop.

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.

The alternative, shown in the FAQ http://matlab.wikia.com/wiki/FAQ#How_can_I_create_variables_A1.2C_A2.2C....2CA10_in_a_loop.3F is more complicated than just using arrays:
counter = 1;
a(counter) = 1;
while a(counter)>0
a(counter) = input('Example')
counter = counter + 1;
end
I think your friend could certainly grasp this concept that even a high school kid could understand.

Yes, you can but your example is not clear using infinite loop and an input each iteration .
for t=1:10
x=t; % each iteration x= t={1,,,,10} x(final)=10
end
