Help Center Help Center. Function signatures describe the acceptable syntaxes and allowable data types for a function. MATLAB is able to provide code completions and suggestions for functions with arguments blocks based on the information contained in the arguments block. This information is available without requiring a functionSignatures. If you define information for a class method or namespace function, place functionSignatures. For example, to define information for a method of myClass , place functionSignatures. For classes located outside of class or namespace folders, place functionSignatures. You can define signatures for multiple functions in the same file. The functionSignatures.
