What Each Block Reference Page Contains

• The block name, icon, and block library that contains the block
• The purpose of the block
• A description of the block's use
• The block dialog box and parameters
• The block characteristics, including some or all of these, as they apply to the block:
  • Direct Feedthrough - whether the block or any of its ports has direct feedthrough. For more information, see "Algebraic Loops".
  • Sample Time - how the block's sample time is determined, whether by the block itself (as is the case with discrete and continuous blocks) or inherited from the block that drives it or is driven by it. For more information, see "Sample Time".
  • Scalar Expansion - whether or not scalar values are expanded to vectors. Some blocks expand scalar inputs and/or parameters as appropriate. For more information, see "Scalar Expansion of Inputs and Parameters".
  • States - the number of discrete and continuous states.
  • Vectorized - whether the block accepts and/or generates vector signals. For more information, see "Vector Input and Output".
  • Zero Crossings - whether the block detects state events. For more information, see "Zero Crossings".
