## @deftypefn {Function File} {} semilogyerr (@var{args})
## Produce two-dimensional plots on a semilogarithm axis with errorbars.
## Many different combinations of arguments are possible.  The most used
## form is
##
## @example
## semilogyerr (@var{x}, @var{y}, @var{ey}, @var{fmt})
## @end example
##
## @noindent
## which produces a semi-logarithm plot of @var{y} versus @var{x}
## with errors in the @var{y}-scale defined by @var{ey} and the plot
## format defined by @var{fmt}.  See errorbar for available formats and 
## additional information.
