Support root-level matrix I/O using one-dimensional arrays

Use one-dimensional C arrays to support root-level matrix I/O

Model Configuration Pane: Code Generation > AUTOSAR Code Generation Options

Description

Allow root-level matrix I/O for column-major array layout

Settings

'off' (default) | 'on'

• 'off' — For column-major array layout, software does not allow matrix I/O at the root level. If you try to build a model that has matrix I/O at the root level, the software produces an error.

• 'on' — For AUTOSAR component models that use column-major array layout, software supports matrix I/O at the root level by generating code that implements matrices as one-dimensional arrays.

Tips

• All models in a model hierarchy must specify the same value for this parameter.

• For an AUTOSAR component model with multidimensional arrays, if you set the model configuration parameter Array layout to Row-major, you can preserve dimensions of multidimensional arrays in the generated C code. Preserving array dimensions in the generated code can enhance code integration.

  When Array layout is set to Row-major, Support root-level matrix I/O using one-dimensional arrays does not apply.

• Models configured for the AUTOSAR Classic Platform do not support multi-dimensional arrays for outports mapped with data access mode ImplicitSendByRef. When you validate the code mappings or try to generate code, the software produces an error if outports mapped with data access mode ImplicitSendByRef are present in the model. Use one-dimensional arrays or select a different data access mode.
