Common Error Types and Troubleshooting

While I wait for your specific details, here are some common MATLAB errors and potential solutions:

Undefined function or variable

• Check spelling: Ensure all variable and function names are correct.
• Verify path: Make sure the function or script is in the MATLAB path.
• Declare variables: Define variables before using them.

Index exceeds matrix dimensions

• Check array size: Verify that the indices you're using are within the array's bounds.
• Use logical indexing: If accessing elements based on conditions, use logical indexing.

Matrix dimensions must agree

• Check matrix sizes: Ensure matrices have compatible dimensions for operations.
• Use appropriate functions: Employ functions like repmat, reshape, or transpose to adjust matrix sizes.

Division by zero

• Check denominators: Avoid dividing by zero by adding conditions or using eps.

Out of memory

• Reduce data size: Consider using smaller data subsets or data types.
• Optimize code: Improve algorithm efficiency.
• Increase memory allocation: If possible, allocate more memory to MATLAB.

Syntax errors

• Check for typos: Verify correct syntax for operators, parentheses, and keywords.
• Use consistent indentation: Improve code readability and reduce errors.

Debugging Tips

• Use the debugger: Step through your code line by line to inspect variables and identify issues.
• Add comments: Explain code logic for better understanding.
• Break down complex code: Divide code into smaller, testable functions.
• Test incrementally: Add code sections gradually and test after each addition.
• Search online resources: MATLAB documentation and forums often provide solutions to common problems.

Exact Error

these are the exact error messages i am getting

Error1: Invalid setting for output port dimensions of 'fccu/Mux6'. The dimensions are being set to 1. This is not valid because the total number of input and output elements are not the same,

Error2: Error:Error in port widths or dimensions. 'Input Port 1' of 'fccu/Zero-Order Hold' is a one dimensional vector with 1 elements.

the simulink file i s uploaded above

i am also going to upload the matlab file,

Expected behavior

what i am trying to do is offset free Nonlinear MPC using comparison of different formulation, so i have a matlab folder that consists of the controller, continuous state equation, discrete equation, the NMPC controller.

Actual behavior

so what i am expecting the code to do is to track setpoint and remove offset but the error above is not allowing the simulation to run and error is only associated with matlab 2024a
