Update gnuplot plotting scripts for faster or more modern synta * scripts/plot/__gnuplot_drawnow__.m: Use default values in function header. Check number of arguments to function immediately. Use single quotes to avoid lots of backslashing. Use strtok() to replace hand-coded functionality. Initialize persistent variables in declaration (10% faster). * scripts/plot/gnuplot_binary.in: Replace tabs with spaces. Simplify input validation. Add %!test block. * scripts/plot/private/__gnuplot_get_var__.m: Use default values in function header. Use "*char" in fread to automatically convert to char variable. * scripts/plot/private/__gnuplot_ginput__.m: Check immediately for required version of gnuplot. Use "*char" in fread to automatically convert to char variable. Use fputs in place of fprintf to match rest of code. * scripts/plot/private/__gnuplot_has_feature__.m: Initialize persistent varibles in declaration. Use false () rather than logical (zeros()) construction. * scripts/plot/private/__gnuplot_has_terminal__.m: Use strtok() to replace hand-coded functionality * scripts/plot/private/__gnuplot_print__.m: Replace sprintf calls with direct string char matrix concatenation (2.4x faster) where possible. Replace for loop with multiple argument form of set(). Use single quotes to avoid lots of backslashing. * scripts/plot/private/__gnuplot_version__.m: Use single quotes to avoid lots of backslashing.

## @deftypefnx {Function File} {@var{jary} =} javaArray (@var{classname}, @var{m}, @var{n}, @dots{})
##
## Create a Java array of size @var{sz} with elements of class
## @var{classname}.  @var{classname} may be a Java object representing a class
## or a string containing the fully qualified class name.  The size of
## the object may also be specified with individual integer arguments
## @var{m}, @var{n}, etc.
##
## The generated array is uninitialized.  All elements are set to null
## if @var{classname} is a reference type, or to a default value (usually 0)
## if @var{classname} is a primitive type.
##
## Sample code:
##
## @example
## @group
## jary = javaArray ("java.lang.String", 2, 2);
## jary(1,1) = "Hello";
## @end group
## @end example
## @seealso{javaObject}
## @end deftypefn
