WitrynaScalar. The number of inputs to the Mux block. When you use this format, the block accepts scalar or vector signals of any size. Simulink ® assigns each input the name signalN, where N is the input port number. Vector. The length of the vector specifies the number of inputs. Each element specifies the size of the corresponding input. Witryna28 mar 2015 · The length is 0 for empty objects, 1 for scalars, and the number of elements for vectors. For matrix objects, the length is the number of rows or columns, whichever is greater (this odd definition is used for compatibility with MATLAB). MATLAB does not have true scalars.
