Does Matlab have a trajectory generator function for 3D movement?

Hi All

I came up with this function

https://de.mathworks.com/matlabcentral/fileexchange/40278-trajectory-generation-3rd-5th-orders

but it is not mentioned if it is a function for a 2D planar movement ora 3D movement

[Walter Roberson]

Those functions are for 2D work.

As those functions are designed for generating coefficients for a polynomial, they are designed for linear movement, cases where the current position can be computed just knowing the output time, with no X Y interaction terms for example.

If you are designing linear movement in 3D, then you can separate that out into two polynomals, each computed by one call each to those functions.

Those functions are not designed to handle interactions. For example those functions cannot be used to design an elliptical (or circular) trajectory.

Is it how in robotics being done? is the trajectroy calculation being called twice?

[Walter Roberson]

No, robotics calculates completely different ways. See for example https://www.mathworks.com/help/robotics/manipulator-motion-planning.html
