plot 3D-graph changing with input data array,problem with " Subscripted assignment dimension mismatch" error

     %global variables
  global x y thetaz rC Rz gamma beta z
  %data division
  x=[-5:1:5];
  y=[-5:1:5];
  z=[10:2:30];
  gamma=[-20:4:20];
  beta=[-20:4:20];
  thetaz=[-20:4:20];

n=numel(x); %check size of data array

hold on
for i = 1:n
  [case1_theta1(i,:),case1_theta2(i,:),rC(i,:),Rz(i,:)]=findangles(x(i),y(i),thetaz(i));
 [L1(i,:),L2(i,:),L3(i,:),rP(i,:)]=findprismaticslength(gamma(i),beta(i),z(i),rC(i),x(i),y(i),Rz(i)); 
    pause(1)         %pause(seconds)
end

note: findangles and findprismaticslength are functions i created to give each data in the form of array too

Which line is the error on?

Why are you using global ? What if something else already initialized those variables?

[Fatefly Yip]

because the data from one function being used by another function,so i have to use global? i just made a guess

[Fatefly Yip]

By chance,i manage to plot it (3D plot),i just removed '(i,:)' from output from each function

%global variables
  global x y thetaz rC Rz gamma beta z
  %data division
  x=[-5:1:5];
  y=[-5:1:5];
  z=[10:2:30];
  gamma=[-20:4:20];
  beta=[-20:4:20];
  thetaz=[-20:4:20];

    n=numel(x); %check size of data array

    hold on
    for i = 1:n
      [case1_theta1,case1_theta2,rC,Rz]=findangles(x(i),y(i),thetaz(i));
     [L1,L2,L3,rP]=findprismaticslength(gamma(i),beta(i),z(i),rC,x(i),y(i),Rz); 
        pause(1)         %pause(seconds)
    end

can i make my input here to be smaller division? says i want x=[-5:0.5:5],which is incremented by 0.5 each time and it gives me 21 data,but i need all other data sets to have same size of array

x=[-5:1:5];
  y=[-5:1:5];
  z=[10:2:30];
  gamma=[-20:4:20];
  beta=[-20:4:20];
  thetaz=[-20:4:20];

If you are wanting combinations of x, y, z, instead of corresponding x, y, z, then you should see ndgrid()

[Fatefly Yip]

thx,i think it is okay now...at least got the plotting moving

[Fatefly Yip]

@Walter Roberson, how can i record the plots(moving) as a video from matlab?
