Simulink Neural Network data input

I have a 2x147 matrix as an input and a 3x147 matrix as an output, and I trained the NN pattern recognition with the input matrix and output matrix. I then generated a Simulink model of the trained NN, and now I want to test the new dataset of same size (2x147).

I am getting the following errors:

Error in port widths or dimensions. Output port 1 of NN_Trail/Constant is a [2x147] matrix.

Error in port widths or dimensions. Input port 1 of NN_Trail/Pattern Recognition Neural Network is a one dimensional vector with 2 elements. If I give a constant value of 2 elements, then the Simulink runs for the mentioned time and gives the desired output. How can I get it to work with the data I've described?

My idea in future is to connect the trained neural network to a simulated plant and find the abnormal data from the plant.
