`desing/coeffC`

Computing the coefficient ideal of the C member of an SBO w.r.t. a list of elements from the IND member of the chart.

Input:

 

C

the corresponding member of an SBO,

z

a list of pairwise different indices to the IND member of the chart of the SBO,

Output:

The coefficient ideal of C w.r.t. z, in the format of the C component of a basic object.

The procedure updates the rational values of the functions in C.
