NAME
       MPSolve - A multiprecision polynomial rootfinder

DESCRIPTION
       mpsolve [-a alg]	[-b] [-c] [-G goal] [-o	digits]	[-i digits] [-j	n] [-t
       type] [-S set] [-D detect] [-O format] [-l  filename]  [-x]  [-d]  [-v]
       [-r] [infile | -p poly]

OPTIONS
       -a alg Select  the algorithm used to solve the polynomial/secular equa-
	      tion:

	      u: Classic unisolve algorithm  (Aberth  iterations  and  dynamic
	      precision)
	      s:  Secular  algorithm,  using regeneration of increasingly bet-
	      ter-conditioned

	      secular equations	with the same roots of the polynomial

       -b     Perform Aberth iterations	in Jacobi-style	instead	of  Gauss-Sei-
	      del

       -c     Enable crude approximation mode

       -G goal
	      Select the goal to reach.	Possible values	are:

	      a: Approximate the roots
	      i: Isolate the roots
	      c: Count the roots in the	search set

       -o digits
	      Number of	guaranteed digits of the roots

       -i digits
	      Digits of	precision of the input coefficients

       -j n   Number of	threads	to spawn as workers

       -t type
	      Type can be 'f' for floating point or 'd'	for DPE

       -S set Restrict the search set for the roots set	can be one of:

	      u: upper half-plane { x |	Im(x) >	0 }
	      d: lower half-plane { x |	Im(x) <	0 }
	      l: left half-plane { x | Re(x) < 0 }
	      r: right half-plane { x |	Re(x) >	0 }
	      i: inside	the unit circle: { x | |x| < 1 }
	      o: outside the unit circle { x | |x| > 1 }
	      R: real axis { x | Im(x) = 0 }
	      I: imaginary axis	{ x | Re(x) = 0	}

       -D detect
	      Detect properties	of the roots:

	      r: real roots
	      i: imaginary roots
	      b: both

       -O format
	      Select format for	output:

	      f: full output
	      b: bare output
	      c: compact output
	      v: verbose output
	      g: gnuplot-ready output
	      gf: gnuplot-full mode, can be piped to gnuplot and display error
	      bars.
	      gp: The same as gf but only with points (suitable	for  high  de-
	      gree polynomials)

	      For example:

	      mpsolve -as -Ogf myfile.pol | gnuplot

       -l filename Set filename	as the output for the log, instead of the tty.
	      Use this option with

	      -d[domains] to activate the desired debug	domains.

       -x     Enable graphic visualization of convergence

       -d[domains] Activate debug on selected domains, that can	be one of:

	      t: trace
	      a: approximation
	      c: cluster
	      i: improvement
	      w: timings
	      o: input/Output
	      m: memory	management
	      f: function calls
	      p: debug stop condition and development of iteration packets
	      r: regeneration Example: -dfi for	function calls and improvement

       -p poly
	      Solve the	polynomial specified on	the command line.

	      For example: mpsolve -p "x^4-6x^9+6/7x + 5"

       -r     Use a recursive strategy to dispose the initial approximations.
	      This option is available only for	monomial polynomials.
	      Note: this option	is considered experimental.

       -v     Print the	version	and exit

SEE ALSO
       The full	documentation for MPSolve is maintained	as a  Texinfo  manual.
       If  the	info and MPSolve programs are properly installed at your site,
       the command

	      info MPSolve

       should give you access to the complete manual.
