Description

People have been asking me for an easy/automated way to create polynomial rings in two sets of varibles such as x0, x1, x2, x3, y0, y1, y2, y3. This patch provides a way to do so: 

sage: PolynomialRing(ZZ, 3, var_array=['x','y'])
Multivariate Polynomial Ring in x0, y0, x1, y1, x2, y2 over Integer Ring
sage: PolynomialRing(ZZ, 3, var_array='a,b')
Multivariate Polynomial Ring in a0, b0, a1, b1, a2, b2 over Integer Ring
sage: PolynomialRing(ZZ, 2, 3, var_array='m')
Multivariate Polynomial Ring in m00, m01, m02, m10, m11, m12 over Integer Ring
sage: PolynomialRing(ZZ, 2, var_array='m')
Multivariate Polynomial Ring in m00, m01, m10, m11, over Integer Ring
