I created a code and am wanting to graph this analytical solution and a modeled solution on the same graph. Currently when I try to graph the data it outputs the table that I imported from a .dat attached is the file.
SH = 45*10^6;
Sh = 30*10^6;
theta = 90;
R = 1;
r = linspace(1,6);
hoop =.5*(SH+Sh)*(1+R.^2./r.^2)-.5*(SH-Sh)*(1+3*R.^4./r.^4)*cos(2*theta);
plot(r, hoop,HW9(:,1),HW9(:,2))
title('Hoop Stress')
xlabel('Distance from wellbore in terms of r')
ylabel('Hoop Values')

Hi Mitchell,
Could you explain a little more about your workflow on what is the exact output you observe and the output that you expect?
Also, can you please attach the .dat file that you are trying to import into MATLAB?

If HW9 is a MATLAB table object then you probably need
plot(r, hoop,HW9{:,1},HW9{:,2})
