Hi kani muhamed,

The errors you are facing while running the code for Vehicle path tracking using MPC can be resolved by following the below steps:

• Resolve the 'velNorm' Parameter Issue by opening the Simulink model and locating the block 'Vehicle XY Plotter'.
• Check for the parameter 'velNorm'and ensure that 'velNorm' is defined either in the MATLAB workspace, a script, or as a mask parameter in the block. If not defined, add the required variable in the workspace.
• Fix the Promoted Parameter Warning by ensuring that all promoted parameters are properly linked to variables or constants in the workspace.
• Fix the Sizes Mismatch Error as this error indicates that the dimensions of a signal or parameter are not matching.
• Check the inputs and parameters in the model for dimensional consistency.
• Verify that all input signals to the block have matching dimensions. Adjust the signal size as needed.
