Hello,
When I try to run the Combined Slip Wheel STI block I get the following error.
"Function 'Combined Slip Wheel STI/Outputs/W-axis to C-axis' (#178.146.161), line 7, column 11: "cross(XeCp, Fw)" "
Below are the inputs of my model (which I belive match the documentation). Any help is appreciated.

Hello,
One final update from me before I put this down for the night: When I connect a 3 zero vector the code runs fine but when I connect the 3 vector generated by my model the error is thrown. See the picture below showing the 3 vectors are the same.

Final Comment: I tired transposing my signal (Xe) before inputting it into the block and it still did not work.

Hi Brandyn Pataki,
One possible reason for encountering the error is because of input dimension mismatch. As per the "Combined Slip Wheel STI" documentation :- https://www.mathworks.com/help/releases/R2022a/vdynblks/ref/combinedslipwheelsti.html#mw_75660c2f-d0b6-4646-af93-75efdc08da14_sep_bvbo42y-2, Port '' expects a vector representing Rotation angle of rim with respect to the wheel center, in .
However, it seems like you are passing a scalar instead of vector. Review the input values and make necessary changes.
Hope this is helpful.
