Data Definition Basics

Data, variables, and functions for code acceleration

Topics

Eliminate Redundant Copies of Variables in Generated Code
Use coder.nullcopy to indicate that the code generator can allocate memory without initializing it.
Reuse the Same Variable with Different Properties
Reuse a variable with different properties when the code generator can determine the properties of each occurrence of the variable.
Data Definition Considerations for Code Generation
Define data in MATLAB^® code intended for code generation.
Variables Definition for Code Generation
Define the class, size, and complexity of variables in MATLAB source code before using them.
Best Practices for Defining Variables for C/C++ Code Generation
Follow guidelines for defining variables in MATLAB code intended for code generation.
Reassignment of Variable Properties
Reassign a variable with a value of different class, size, or complexity.
Supported Variable Types
Use data types that code generation supports.
Code Generation for Complex Data
Use complex data in MATLAB code intended for code generation.
Code Generation for Sparse Matrices
Use sparse matrices in MATLAB code intended for code generation.
Array Size Restrictions for Code Generation
The code generator and the target hardware constrain the maximum number of elements of an array.
