トピック

入門

What Is Code Replacement Customization?

Customize how and when the code generator replaces C/C++ code that it generates for functions and operators.

Code You Can Replace from MATLAB Code

Review lists of functions and operators the code generator can replace depending on the code replacement library that you specify.

Quick Start Library Development

Develop a code replacement library that includes an entry for generating replacement code for a math function.

コード置換ライブラリを開発するワークフロー

Develop a Code Replacement Library

Workflow for developing a code replacement library.

より詳細な制御のオプション

Data Alignment for Code Replacement

Define code replacement mappings that align data for a replacement function to a specified boundary.

Array Layout and Code Replacement

Define code replacement mappings that specify data layout for storing array elements in memory.

Allow Shape Agnostic Match

Shape-agnostic matrix replacement for Embedded Coder CRL.

Reserved Identifiers and Code Replacement

C/C++ programming language reserved keywords as identifiers and function names in code replacement entries.

Remap Operator Output to Function Input

Meet specific generated code patterns by remapping operator outputs to input positions in your replacement function argument list.

Customize Match and Replacement Process

Add logic to the code replacement match and replacement process for functions or operators.

トラブルシューティング

Troubleshoot Code Replacement Library Registration

If a code replacement library is not listed as a configuration option or does not appear in the Code Replacement Viewer, troubleshoot the library registration.

Troubleshoot Code Replacement Misses

Use miss reason messages that appear in the Code Replacement Viewer to analyze and correct code replacement misses.
