Signal Attributes and Indexing

Inspect and modify data and signal attributes and select data subsets

Inspect and modify signal attributes such as sample time, complexity, dimensions, and data type using the signal attributes and conversion blocks in DSP System Toolbox™. You can also select subsets of data and deconstruct signals using the various selector blocks, and modify this data using the Flip and Overwrite Values blocks.

Signal Attributes and Conversion

Check Signal Attributes	Error when input signal does or does not match selected attributes exactly
Inherit Complexity	Change complexity of input to match reference signal
Data Type Conversion	Convert input signal to specified data type
Reshape	Change dimensionality of signal

Indexing

Flip	Flip input vertically or horizontally
Multiport Selector	Distribute arbitrary subsets of input rows or columns to multiple output ports
Overwrite Values	Overwrite submatrix or subdiagonal of input
Selector	Select input elements from vector, matrix, or multidimensional signal
Variable Selector	Select subset of rows or columns from input
