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.

Oh thank you yeah it works. I was struggling to vectorize the codee. I was wondering if it is possible to plot the values, so it is easier to read them?

%if true
plot(c,Cc,c,Cl,'-r', 'linewidth',2); grid

You can try other options with plot command as well at

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