Matlab Block Error problem

For an assignment, I have to create a crank based on a previous example, and I change the values of the example, but when I key it in after providing the constants, the following error messages come up even though they don't in the original equation, and I have keyed in legitimate values, though one of them has an e04.

      % Error in port widths or dimensions. Output port 1 of 'slrcrndyn2/leocrank.m' is a one dimensional vector with 1 elements.

The code for the matrix is attached. Can the error be explained as soon as possible.
