arbitrary precision linear algebra

2011-03-02 Thread Ben123
Hello. I have a written Python program which currently uses numpy to perform linear algebra operations. Specifically, I do matrix*matrix, matrix*vector, numpy.linalg.inv(matrix), and linalg.eig(matrix) operations. Now I am interested in allowing arbitrary precision. I have tried gmpy, bigfloat, mpm
