I am very interested in using the "phc.module", which is a module to work with "polynomial homotopy continuation" method. Please, see this paper
I have downloaded the following files: [copied without permission, deleted by moderator]
Then, I open (as an "ordinary" maple worksheet) the file "phc_savelib.maple" and execute it, but it seems that I can not use their functions and procedures because it returns errors.
For instance, follwing the attached PDF, in the phc_savelib.maple file, define the polynomial system:
T := makeSystem([x, y], , [x^2+y^2-1, x^3+y^3-1])
and try to solve the above system
sols := solve(T)
but returns the error
Error, (in fopen) file or directory does not exist
Many thanks in advance for your help!
