MATLAB Function and MATLAB Code Considerations

R2026b

MATLAB Functions, MATLAB^® code

Apply high-integrity guidelines for MATLAB Functions and MATLAB code.

Modeling Guidelines

MATLAB Functions

himl_0001: Usage of standardized MATLAB function headers	Use a standardized header to document the purpose and use of MATLAB functions
himl_0003: Complexity of user-defined MATLAB Functions	Limit the size and complexity of MATLAB function code
himl_0002: Strong data typing at MATLAB function boundaries	Explicitly define the complexity and type of input signals, output signals, and parameters at MATLAB function interfaces

MATLAB Code

himl_0004: MATLAB Code Analyzer recommendations for code generation	Use MATLAB Code Analyzer with `%#codegen` directive and follow code generation recommendations
himl_0006: MATLAB code if / elseif / else patterns	Terminate `if`/`elseif`/`else` constructs with an `else` statement containing meaningful comment
himl_0007: MATLAB code switch / case / otherwise patterns	Include at least two case statements and an otherwise statement with a meaningful comment in switch constructs
himl_0008: MATLAB code relational operator data types	Use the same data type for left and right operands of relational operators
himl_0010: MATLAB code with logical operators and functions	Use logical data types for logical operators and logical functions
himl_0011: Data type and size of condition expressions	Use logical scalars for condition expressions
himl_0012: Usage of MATLAB functions for code generation	Restrict MATLAB code to functions supported by code generation
himl_0013: Limitation of built-in MATLAB Function complexity	Limit built-in MATLAB function usage that may produce overly complex generated code
