I am trying to solve the following problem.
y = ((x.*20000)/(x+20000))/10000*2
where x goes from 1 to 20000 with 0.1 jumps.
But i do not get several y's, i only get one.
y = ((x.*20000)/(x+20000))/10000*2
y =
1.4247
i would like to plot the answers but that is a bit hard when i only get on y.
Hope someone knows where the problem could be.

Hi
If you want the division element by element you must put the dot in the right position:
y = ((x*20000)./(x+20000))/10000*2;
