I have a question about "Error in port widths or dimensions. 'Output Port 1' of 'From32' is a one demensional vector with 3 elements" and "Error in port widths or dimensions. 'Input Port 2' of 'Alpha-Beta-Zero to dq0' is a one dimensional vector with 1 elements.".

I wanna know why these errors occurred.

I don't know how to solve these errors.

Please help me solve these errors.

This picture is a circuit that I made.

Yellow From Block is 'From32' and Alpha-Beta-Zero to dq0 is the block connected to 'From32'

I'm using MATLAB R2021b version.

Park Transformation block only accepts a positive scalar for The angular position of the rotating frame is given by the input wt, in rad. You are feeding in a vector with 3 elements.
