Conversion changes of out-of-range numbers passed to Java methods

that take integers

MATLAB R2013b changes the way it converts out-of-range values for the following Java

integer types:

• Signed 32-bit integer (Java int, short or byte parameters)

• Signed 64-bit integer (Java long parameters)

For a description of the conversion, see Converting Numbers to Integer Arguments.

Compatibility Considerations

If your MATLAB code can pass out-of-range values to Java methods with integer type

arguments, the results might change. For example, the following value, val, is out-of-

range for the argument to java.lang.Integer.

val = uint32(2^31);

java.lang.Integer(uint32(val))

In previous versions of MATLAB, the result is:

ans =

-2147483648

As of MATLAB R2013b, the result is:

ans =

-1

Additional properties for mex.getCompilerConfigurations

function

• ShortName — Character string used to identify options file for the compiler

• MexOpt — Name and full path to options file

• Priority — The priority of this compiler
