MATLAB Features That Code Generation Supports

Code generation from MATLAB® code supports many major language features including:

• n-dimensional arrays (see Array Size Restrictions for Code Generation)
• matrix operations, including deletion of rows and columns
• variable-size data (see Code Generation for Variable-Size Arrays)
• subscripting (see Incompatibility with MATLAB in Matrix Indexing Operations for Code Generation)
• complex numbers (see Code Generation for Complex Data)
• numeric classes (see Supported Variable Types)
• double-precision, single-precision, and integer math
• enumerations (see Code Generation for Enumerations)
• fixed-point arithmetic
• program control statements if, switch, for, while, and break
• arithmetic, relational, and logical operators
• local functions
• persistent variables
• global variables (see Specify Global Variable Type and Initial Value Using the App)
• structures (see Structure Definition for Code Generation)
• cell arrays (see Cell Arrays)
• tables (see Code Generation for Tables)
• timetables (see Code Generation for Timetables)
• characters (see Encoding of Characters in Code Generation)
• string scalars (see Code Generation for Strings)
• categorical arrays (see Code Generation for Categorical Arrays)
• datetime arrays (see Code Generation for Datetime Arrays)
• duration arrays (see Code Generation for Duration Arrays)
• sparse matrices (see Code Generation for Sparse Matrices)
• function handles (see Function Handle Limitations for Code Generation)
• dictionaries (see Generate Code for Dictionaries)

MATLAB Language Features That Code Generation Does Not Support

Code generation from MATLAB does not support the following frequently used MATLAB features (this list is not exhaustive):

• scripts
• GPU arrays
  MATLAB Coder™ does not support GPU arrays. However, if you have GPU Coder™, you can generate CUDA® MEX code that takes GPU array inputs.
• calendarDuration arrays
• Java®
• Map containers
• time series objects
• tall arrays
• try/catch statements
• import statements
• pattern arrays
