MATLAB: Plotting a point in 3D

3d plots

How i can i plot the New_P in 3D

i'm using robotic toolbox peter corke

i should use trplot() function but it's not working

 P = transpose([2,3,4,0]);
 New_P = trotx(45) * P

Best Answer

You can draw this point using plot3()

P = transpose([2,3,4,0]);
New_P = trotx(45) * P;
plot3(New_P(1), New_P(2), New_P(3), '+');

Ee = [-P(1)  e0  -P(3) P(2)
      -P(2)  P(3) e0  -P(1)
      -P(3) -P(2) P(1) e0];
  
  i = 0;        % adding counter index
  for it=2:4:52
      i = i + 1;
EeNew(1:3,1:4,i) = [-P(it+3)  P(it+2) -P(it+5)  P(it+4)    % storing evaluated matrices along the 3rd dim.
         -P(it+4)  P(it+2)  P(it+2) -P(it+3)
         -P(it+5) -P(it+4)  P(it+3)  P(it+2)];
  end
  EeNew = EeNew(:,:);                        % flattening 3rd dimension to make 3x(4*k) final matrix

Not sure i completely understood you question but maybe this is what you are looking for ?

MATLAB: How to plot matrix inside for loop

Like this?

A = [0 3/10;3/5 0];
u = [0.3 ;0.8]; 
p = nan(2,51);
% Inisital condition
p(:,1) = [0;0];
for n=1:50
 p(:,n+1) = A*p(:,n) + u;
end
% Plot the result
figure
plot(0:50,p(1,:))
hold on
plot(0:50,p(2,:))
