This page describes the usage of MPSolve.
The executable program of the package is called unisolve (univariate polynomial solver).
There are 3 main ways of running MPSolve:
1. reading from the standard input stream (typically the keyboard).
(one can type here for example content of the file mand31.pol, without comments line, which start with "!" character )
2. reading from input file (holding the input polynomial in the form: degree and list of coefficients)
3. using "user defined" polynomials. In this case one uses 2 files:
- mps_user.c (containing definition of polynomial in the form of recurrence relation)
- input file containing only degree of polynomial
compare the files mand31.pol and umand31.pol to see the differences. The output files should be the same.
If one wants to use other type of "user defined" polynomial than this one which is contained in the standard mps_user.c file, then should:
- edit usr_mand.c and modify the code in order to obtain the implementation of the polynomial that you want
- copy usr_mand.c into mps_user.c ( it should be readable and writable by the user)
- run make ( to recompile the package)
- write the desired degree of polynomial in the input file (here for example: umand31.pol )
- run MPSolve ( the way number 3)
In all above examples output will be on the screen.
If one wants to save the output to the text file with res extension in directory Results:
./unisolve Data/umand31.pol >Results/umand31.res
Ploting the data from output file in gnuplotEdit
First create file for gnuplot ( use -Og option ), for example:
./unisolve -Og Data/umand31.pol >Results/umand31g.res
and inside gnuplot:
To save plot in postscript file:
set term postscript set output "umand31.eps" plot "/home/adam/mpsolve/MPSolve-2.2/Results/umand31g.res"
To go back to the normal output (screen - X Window plotting terminal), then :
set term x11
