Passing Data to a Java Method
5-47
scalar (1-by-1) arrays or matrices. All of the Java types can be scalar values or
arrays.
Data type conversion of arguments passed to Java code will be discussed in the
following three categories. MATLAB handles each category differently.
•“Passing Built-In Data Types”
•“Passing String Arguments”
•“Passing Java Objects”
