Error: Error using surf (line 78) Data dimensions must agree

for i= 0:0.05:5.58 %5.58

q = [i 0 0 0 0 0]
r = p560.fkine(q)

x= r(1,4);
y = r(2,4);
z = r(3,4);

 X = [X;x]
 Y = [Y;y]
 Z = [Z;z]
Please Help!

[Anjali Rao]

I want to find the workspace for the manipulator, I am able to plot the path of end effector for all angles.Please guide!

[Jan]

Please post the relevant part of the plot (where is the failing surf command?!) and the complete error message. Is "r" a variable of a function? What is "p560.fkine"?

Please post the required details.

As Jan Simon noted, we'll need more information to fully help you.

However, based on your provided code, I'm going to assume your "surf" call is of the form "surf(X,Y,Z)" and that X and Y are vectors. Thus, according to the documentation, the key point is that

If X and Y are vectors, length(X) = n and length(Y) = m, where [m,n] = size(Z).
