23 ## Query or set the internal variable that controls how integer classes are
24 ## converted when Java matrix autoconversion is enabled. When enabled, Java
25 ## arrays of class Byte or Integer are converted to matrices of class uint8 or
26 ## uint32 respectively.
27 ##
28 ## When called from inside a function with the @qcode{"local"} option, the
29 ## variable is changed locally for the function and any subroutines it calls.
30 ## The original variable value is restored when exiting the function.
