Find Nonzero Elements
Find nonzero elements in array
- Library:
Simulink / Math Operations
Description
The Find Nonzero Elements block locates all nonzero elements of the input signal and returns the linear indices of those elements. If the input is a multidimensional signal, the Find Nonzero Elements block can also return the subscripts of the nonzero input elements. In both cases, you can show an output port with the nonzero input values.
The Find Nonzero Elements block outputs a variable-size signal. The sample time for any variable-size signal must be discrete. If your model does not already use a fixed-step solver, you may need to select a fixed-step solver in the Configuration Parameters dialog. For more information, see Compare Solvers and Choose a Solver.
