Hi, I am having trouble with plotting five figures from one 7 by 20 matrix, where the first four columns denote the x coordinates of the four lines of the first figure, the second four columns denote the x coordinates of the four lines of the secong figure, etc. I have tried something as follows:
pstar = cell2mat(pStar);
N2 = 5;
for i5 = 0:N2:((N2*N2)-1)
pstar1 = pstar(:,i5+1);
pstar2 = pstar(:,i5+2);
pstar3 = pstar(:,i5+3);
pstar4 = pstar(:,i5+4);
end
which would give me a figure on using:
% pStar plot
figure(3)
plot(pstar1,X1,'+')
hold on
plot(pstar2,X1,'+')
plot(pstar3,X1,'+')
plot(pstar4,X1,'+')
hold off
title('Radial Distribution of Dimensionless Pressure')
xlabel('p*')
ylabel('x')
legend('{C}_{{w}_{1}}','{C}_{{w}_{2}}','{C}_{{w}_{3}}','{C}_{{w}_{4}}')
grid
where the y coordinates are: X1 = 0.4000 0.5000 0.6000 0.7000 0.8000 0.9000 1.0000 , corresponding to each of the seven rows, and the matrix:
pstar =
