I am wondering why I get the following error message. There is no problem with the signal dimension as shown.Also, I am not using any Matlab-defined function. The block B includes a "Matrix Multiplier" and the rest are constant, gain, sum and integral blocks. The constant and gain are in the form of vectors or matrices but they do not violate matrix multiplication or summation rules regarding their dimension. Any idea? Thanks for your time and your reply
Error: "Unable to determine signal dimensions. There is a loop consisting of '....' that cannot be resolved because signal dimensions are defined by a cyclic relationship. Specifying the signal dimensions on Inport, Mux, Selector, Demuxes will help resolve signal dimensions in the loop. You can also use the Signal Specifications to define the signal dimensions."

Please let me know how to make your answer as accepted. I cannot find that option.

I note that in Subsystem B that y3 is 1 x 4 but is received in the sum block as 4 x 1; I do not know at the moment if that would be a problem.
