Signal Attributes and Indexing
R2026bInspect 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.
Blocks
 | 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 |
 | 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 |
