MATLAB/simulink报错

Question

Unable to determine signal dimensions. There is a loop consisting of 'wrwer/ctr/sgn1/Mux' 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.

Answer 1

信号维度错误，用Signal Specifications去定义下信号的维度。
