#### D.15.25.4 cccMatrixToPositiveIntvec

Procedure from library `tropicalNewton.lib` (see tropicalNewton_lib).

Usage:
cccMatrixToPositiveIntvec(M); M matrix

Return:
intvec, strictly positive equivalent as weight vector to row vector in M

Assume:
constant coefficient case only,
will scale weight vector and add vectors of ones to it

Example:
 ```LIB "tropicalNewton.lib"; ring r = (0,t),(p01,p02,p12,p03,p13,p23,p04,p14,p24,p34),dp; number uniformizingParameter = t; export(uniformizingParameter); ==> // ** `uniformizingParameter` is already global ideal I = p23*p14-p13*p24+p12*p34, p23*p04-p03*p24+p02*p34, p13*p04-p03*p14+p01*p34, p12*p04-p02*p14+p01*p24, p12*p03-p02*p13+p01*p23; system("--random",1337); matrix p = tropicalPointNewton(I); print(p); ==> -59,-14,-87,57,-16,-63,41,-32,-90,-8 intvec w = cccMatrixToPositiveIntvec(p); print(w); ==> 32, ==> 77, ==> 4, ==> 148, ==> 75, ==> 28, ==> 132, ==> 59, ==> 1, ==> 83 def s = switchRingsAndComputeInitialIdeal(I,w); kill uniformizingParameter; ```
