I would like to simulate an equation and plot a graph from the calculated values, but I'm not sure how to proceed to store the values of each iteration in the for-loop.
Any tips would be appreciated.
k = -1.9;
R = -1.6;
for r = 0.00 : 0.10 : 1.60
fr = r/R;
squrt = 1 - ((1 + k)* fr^2);
z = ((r^2)/R)/(1 + sqrt(squrt));
% from this point on I'm not sure how to proceed. how do i store each
% value into a matrix?
end
Thank you in advance.

Hey You can refer to the plotting documentation. Considering you needed a z vs r graph, heres the code and the plot. Hope this helps.
k = -1.9;
R = -1.6;
for r = 0.00 : 0.10 : 1.60
fr = r/R;
squrt = 1 - ((1 + k)* fr^2);
z = ((r^2)/R)/(1 + sqrt(squrt));
%plotting
plot(r,z,'.');
hold on
end
