My for loop is only running one time and M_Star2 and M_Star should be a 1x41 matrix but it only comes out as one number. Here is my code: Solution??
clc
clear workspace
gamma = 1.4;
M = 3:0.1:7;
for ii = 1:size(M);
P_staticRATIO = 1 + (2*gamma/gamma+1)*((M.^2)-1);
P_stagRATIO = (((((gamma+1)^2)*M.^2)/(4*gamma.*(M.^2))-2*(gamma-1)).^3.5)*(((-.4)+2*gamma.*M.^2)/2.4);
M_star2 = ((gamma+1).*M.^2)/(2+(gamma-1).*M.^2);
M_star = sqrt(M_star2);
plot(P_staticRATIO,P_stagRATIO,P_staticRATIO,M_star);
legend('Stagnation Pressure Ratio','M*')
title('M* & Stagnation Pressure Ratio as a Funciton of Static Pressure Ratio')
xlabel('Static Pressure Ratio')
ylabel('M*, Stag. Pressure Ratio')
end

the size function returns a vector [1 41] which is why the loop only runs once.
Use:
for ii = 1:max(size(M));
