N-dimensional arrays.

Matrix operations, including deletion of rows and columns.

Variable-size data(seeGenerate Code for Variable-Size Data). Comparison plotting does not support variable-size data.

Subscripting (seeIncompatibility with MATLAB in Matrix Indexing Operations for Code Generation).

Complex numbers (seeCode Generation for Complex Data).

Numeric classes (seeSupported Variable Types).

Program control statementsif,switch,for,while, andbreak.

Arithmetic, relational, and logical operators.

Local functions.

Global variables.

Persistent variables.

Structures.

Characters.

Single-precision conversion does not support the complete set of Unicode^®characters. Characters are restricted to 8 bits of precision in generated code. Many mathematical operations require more than 8 bits of precision. If you intend to convert your MATLAB algorithm to single precision, it is a best practice not to perform arithmetic with characters.

MATLAB classes. Single-precision conversion supports:

It does not support class inheritance or packages.

Single-precision conversion usingcodegenwith the-singleCoption does not support classes when the properties have default values. Property values must be initialized in the constructor. Constant properties cannot be initialized to double precision data types.

Function calls (seeResolution of Function Calls for Code Generation)

vararginandvarargoutare supported when you generate single-precision C/C++ code by using theMATLAB Coder™app orcodegenwith-singleC. They are not supported when you usecodegenwith-double2single.

For functions that do not usevararginorvarargout, you can control the number of input or output arguments in the generated entry-point function only if you generate single-precision C/C++ code by using theMATLAB Coderapp orcodegenwith-singleC.
