3d track plot in Matlab (ex-embedded) Function block
显示 更早的评论
Hi,
I connected x,y,z coordinates in my custom matlab function block and I used this code:
function out = fcn(x,y,z)
%#codegen
coder.extrinsic('plot3')
coder.extrinsic('grid')
coder.extrinsic('axis')
plot3(x,y,-z, 'or')
axis([0 1 -0.0001 0.0001 -1 0])
grid on
out = [x,y,z];
(with a Terminator block in the output port)
to plot a trajectory, but it plots a dot since it updates itself as one at a time. How can I draw a trajectory as track in the space (I want make it store previous coordinates) ?

Save your data to workspace, then plot what you want!

I think Embedded function don't support hold on comand, use instead Matlab function block
