What Each Block Reference Page Contains
Blocks appear in alphabetical order and contain some or all of this information:
- The block name, icon, and block library that contains the block
- The purpose of the block
- A description of the block's use
- The data types and numeric type (complex or real) accepted and generated by the block
- The block dialog box and parameters
- The rules for some or all of these topics, as they apply to blocks with fixed-point capabilities:
- Converting block parameters from double precision numbers to Fixed-Point Blockset data types.
- Converting the input data type(s) to the output data type.
- Performing block operations between inputs 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 arrays. 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.
- Dimensionalized- whether the block accepts and/or generates multidimensional signal arrays. For more information, see Signal Basics.
- Zero Crossings - whether the block detects zero-crossing events. For more information, see Zero Crossing Detection.
