# nested loops for 2 different variables

This is the code I am trying to run, and I am unsure what is wrong with my nested loops.
Context: I am trying to the find the different values of c and l and calculate the associated costs Cc and Cl for both values . Ultimately I'd like to plot both results to see which combinations of c and l are cheapest. Thank you.
clc;clear;
a=0;
c= 200:10:1200;
l= 1:0.5:7;
for i=1:length(c)
for j=1:length(l)
Cc = (10*c)-2000;
Cl = 900+825*l.^2-1725*l;
a=a+c+l;
end
end

I actually think vectorizing the code would be much faster? am i right?

%if true
clc;clear;
a=0;
c= linspace(200,1200,20);
l= linspace(1,7,length(c));
for i=1:length(c)
Cc(i) = (10*c(i))-2000;
Cl(i) = 900+825*l(i)^2-1725*l(i);
end
Vectorizing could be faster but it can also work with loops better.

Is it possible to plot these values on a 3D plot?
