Vector Input and Output
Almost all Simulink blocks accept scalar or vector inputs, generate scalar or vector outputs, and allow you to provide scalar or vector parameters. These blocks are referred to in this manual as being vectorized. You can determine which lines in a model carry vector signals by choosing Wide Vector Lines from the Format menu. When this option is selected, lines that carry vectors are drawn thicker than lines that carry scalars. The figures in the next section show scalar and vector lines. If you change your model after choosing Wide Vector Lines, you must explicitly update the display by choosing Update Diagram from the Edit menu. Starting the simulation also updates the block diagram display. Block descriptions in Chapter 8 discuss the characteristics of block inputs, outputs, and parameters.
