Hi,
I stored some data in two column matrix, named "Shear", the results are correct. But how to plot this data in a correct way? I want the left column data on the x-axis (0m...26.6m) corresponding with the second column data on the Y-axis.
The command "plot(Shear)" gives not the correct result at all.
Thanks in advance
syms Z
X=0
while X<=0.5
Shear =[X,(q)/(2*h)*int((((sin(omega))^2+(h^2)*(Z^2+Y^2-2*Z*Y*cos(omega)))^(1/2)),Z,26.6,26.6-X)];
disp(Shear);
X = X+0.1;
end
plot(Shear)

Try:
plot(Shear(:,1),Shear(:,2));
If you give a matrix as an argument to plot() it will draw each column as independent data.
Read the documentation for more details:
doc plot;

You should use Shear=[Shear,... instead of Shear=[X,..
Shear=0;X=0;
while X<=0.5
Shear =[Shear,(q)/(2*h)*int((((sin(omega))^2+(h^2)*(Z^2+Y^2-2*Z*Y*cos(omega)))^(1/2)),Z,26.6,26.6-X)];
X=X+0.5
end
