[Paul K. <pki...@ja...>]

octave-forge 2002-11-30 release.

Now requires octave-2.1.40 to work correctly.  
Some functions may work with older versions of Octave.  
Use make -k to build whatever can be built ignoring the rest.

New functions

        * general/ndims: compatibility function
        * image/imginfo: determines size of image using 'convert'
        * image/colfilt: image block filtering function
        * image/im{rotate,translate,shear}: image transformations
        * miscellaneous/inline: generate a function from an expression
        * miscellaneous/slurp_file: loads a file into a string
        * miscellaneous/{rotv,rotparams}: parameterize 3D rotation matrices
        * plot/contour.f: filled contours
        * sparse/{sprand,spdiags,issparse}: sparse functions
        * specfun/lambertw: Lambert's W function: x=w(x)*exp(w(x))
        * specfun/betaln: log beta
        * splines/pchip: Piecewise Cubic Hermitian Interpolating Polynomial
        * statistics/{boxplot,scatter}: statistical plots
        * symbolic/{cheb,chebwin}: Dolph-Chebyshev windows
        * vrml/vmesh: 3D visualization of a surface
        * vrml/*: represent and show 3D objects as VRML code (needs FreeWRL)

Extended interfaces

        * audio/au{load,save}: support floating point .wav formats
        * image/colorgradient: allow instantaneous transitions (weight 0)
        * optim/wpolyfit: option to fit through origin
        * signal/{ellip,ellipord}: compatible interfac
        * sparse/spy: accept dense matrices
        * strings/mat2string: accept [] and complex
        * symbolic/*: relational operators
        * time/datestr: more format codes; handle vectors of dates

Changed interfaces

        * image/bwlabel: C++ version---may be different from m-file interface
        * extra/ode: moved from v1.06 to v1.14
        * optim/*: unified interface supporting options
        * optim/wpolyfit: don't return yf
        * optim/wpolyfit: return row vectors for compatibility with polyfit
        * signal/nellip: replaced by ellip, ellipord
        * OCTAVE_FORGE_VERSION is now an ordered integer: yyyymmdd
	* FIXES/fsolve: removed because it hasn't been updated to 2.1.40

extra/tsa

        * significance test and confidence intervals for PACF
        * added histogram functions for multicolumn data
        * support for new releases of octave and matlab
        * bug fixes

extra/NaN

        * added TRIMEAN, NORMPDF, NORMCDF and NORMRND
        * extended NANTEST

        * faster RANKS
        * support for new releases of octave and matlab

Internal changes

        * extra/symband: eigenvector bug removed
        * io/dlmread: returned matrix was transposed
        * general/rat: display 1/0 for infinity
        * plot/ginput: m-file version based on grab.cc
        * plot/legend: give gnuplot time to respond to parameter request
        * signal/{buttord,fir1}: bug fixes
        * sparse/spy: prettier graph
        * gcc 3.2 updates
        * octave 2.1.40 updates
        * remove functions and fixes that are now in octave

Administration
