.NET Data Types inMATLAB

Data conversion, pass data between MATLAB^®and .NET

When you call a .NET method or function, MATLAB automatically converts most primitive MATLAB arguments into .NET types. To pass an array of strings, use thecellfunction. To pass arrays of other MATLAB types, use theNET.createArrayfunction. You cannot pass structure arrays, sparse arrays, or complex numbers to .NET methods.

MATLAB automatically converts primitive .NET return types to equivalent MATLAB types, if they exist. To convert aSystem.Stringobject, call thecharfunction. If the .NET function returns an array, before using the data in a MATLAB command, use the corresponding MATLAB numeric function for rectangular arrays, or thecellfunction for jagged arrays.

Functions

`NET.createArray`	数组nonprimitive .NET types
`NET.disableAutoRelease`	Lock .NET object representing RunTime Callable Wrapper (COM wrapper)
`NET.enableAutoRelease`	Unlock .NET object representing RunTime Callable Wrapper (COM wrapper)
