Support: non-finite numbers

Description

Specify whether to generate non-finite data and operations on non-finite data.

Category: Code Generation > Interface

Settings

Default: on

On

Generates non-finite data (for example, NaN and Inf) and related operations.

Off

Does not generate non-finite data and operations. If you clear this option, an error occurs if the code generator encounters non-finite data or expressions. The error message reports offending blocks and parameters.

Note

Code generation is optimized with the assumption that non-finite data are absent. However, if your application produces non-finite numbers through signal data or MATLAB^® code, the behavior of the generated code might be inconsistent with simulation results when processing non-finite data.

Dependencies

For ERT-based targets, parameter Support: floating-point numbers enables Support: non-finite numbers.
If off for top model, must be off for referenced models.
When you select parameter MAT-File Logging, you must also select Support: non-finite numbers and, if you use an ERT-based system target file, Support: floating-point numbers.
