.NET Data Types in MATLAB
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 the cell
function. To pass arrays of other MATLAB types, use the NET.createArray
function. 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 a System.String
object, call the char
function. 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 the cell
function for jagged arrays. To convert a MATLAB dictionary to a corresponding .NET object, call the NET.createDictionary
function.
