Define a variable?
显示 更早的评论
Hello,
I want to plot n spheres. Its working but the variable k is always red underlined because I didnt defined it before the loop. How can I define this variable?
for i = 1:n
k(i) = surf(r*x+p(i,1),r*y+p(i,2),r*z+r);
end

The red underline occurs when you have not preallocated your array (or matrix).
You can just do
k = zeros(1,n);
for i = 1:n
k(i) = surf(r*x+p(i,1),r*y+p(i,2),r*z+r);
end
and this should solve your problem.
