feather.m: Overhaul function for Matlab visual compatibility. * scripts/plot/feather.m: Reduce length of arrowhead size to 0.20 of arrow shaft. Change arrow head angle with shaft from 45 to 30 degrees. Use variable 'h' instead of 'retval' to match documentation. Redo input validation. Add %!error input validation tests.

## Display a dim-vector object.

define display-dims
  echo ndims: \ 
  output $arg0.rep[-1]
  echo \ndims: \ 
  output *$arg0.rep@$arg0.rep[-1]
  echo \n
  dont-repeat
end

document display-dims
Usage: display-dims DIM_VECTOR
Display the contents of an Octave dimension vector.
end

############################################################
## Display a dense array object.

define display-dense-array
  echo array object: \ 
  output $arg0
  echo \ndimensions:\n
  display-dims $arg0.dimensions
  echo \nrep = \ 
  output *$arg0.rep
  echo \nrep.data = \ 
  output *$arg0.rep.data@$arg0.rep.len
  echo \n
  dont-repeat
end

document display-dense-array
Usage: display-dense-array ARRAY
Display the contents of an ordinary, i.e., dense Octave array.

See also [display-sparse-array] for showing the contents
of sparse Octave arrays.
end

############################################################
## Display a sparse array object.

define display-sparse-array
  echo sparse object: \ 
  output $arg0
  echo \ndimensions.rep[0] = \ 
  display-dims $arg0.dimensions
  echo \ndimensions.rep[1] = \ 
  output $arg0.dimensions.rep[1]
  echo \nrep = \ 
  output *$arg0.rep
  echo \nrep.d = \ 
  output *$arg0.rep.d@$arg0.rep.nzmx
  echo \nrep.r = \ 
  output *$arg0.rep.r@$arg0.rep.nzmx
  echo \nrep.c = \ 
  output *$arg0.rep.c@($arg0.rep.ncols+1)
  echo \n
  dont-repeat
end

document display-sparse-array
Usage: display-sparse-array SPARSE_ARRAY
Display the contents of a sparse Octave array.

See also [display-dense-array] for showing the contents
of ordinary Octave arrays.
end

## Display Octave debugging stack 

define show-octave-dbstack
  call show_octave_dbstack ()
end

document show-octave-dbstack
Usage: show-octave-dbstack
Display the contents of the current Octave debugging stack.

This is the function stack that the Octave interpreter is processing
and will be different from the C++ stack being debugged with gdb.
