DSP Blockset

Statistics

The Statistics library provides fundamental statistical operations such as minimum, maximum, mean, variance, and standard deviation. Most blocks in the Statistics library support two types of operations:

• Basic operations
• Running operations

The blocks listed below toggle between basic and running modes using the Running check box in the parameter dialog box:

• Histogram
• Mean
• RMS
• Standard Deviation
• Variance

An unchecked Running box means that the block is operating in basic mode, while a checked Running box means that the block is operating in running mode.

The Maximum and Minimum blocks are slightly different from the blocks above, and provide a Mode parameter in the block dialog box to select the type of operation. The Value and Index, Value, and Index options in the Mode menu all specify basic operation, in each case enabling a different set of output ports on the block. The Running option in the Mode menu selects running operation.

The following sections explain how basic mode and running mode differ:

• Basic Operations
• Running Operations

The statsdem demo illustrates the operation of several blocks from the Statistics library.
