MATLAB® supports functions with both variable number of
input arguments (varargin) and variable number
of output arguments (varargout).
MATLAB Production Server™ Java® client supports the ability
to work with variable-length inputs (varargin)
and outputs (varargout). varargin supports
one or more of any data type supported by MATLAB. See the MATLAB
Function Reference for complete information on varargin and varargout.
For example, consider this MATLAB function:
function varargout = vararginout(double1, char2, varargin)
double1)
and the second input type is a char (char2). The
third input is a variable-length array that can contain zero, or one
or more input parameters of valid MATLAB data types.The corresponding client method signature must include the same number of output arguments as the first input to the Java method.
Therefore, the Java method signature supported by MATLAB Production Server Java client,
for the varargout MATLAB function, is as follows:
public Object[] vararginout(int nargout, double in1, String in2, Object... vararg);
In the vararginout method signature, you
specify equivalent Java types for in1 and in2.
The variable number of input parameters is specified in Java as Object...
vararg.
The variable number of output parameters is specified in Java as
return type Object[].
Note the following coding best practices illustrated by this example:
Both the MATLAB function signature and the Java method
signature using the name vararginout. Both signatures
define two inputs and two outputs.
MATLAB Java interface supports direct conversion from Java double array to MATLAB double array and from Java string to MATLAB char array. For more information, see Conversion of Java Types to MATLAB Types and Conversion of MATLAB Types to Java Types.
