matrix(Ring,{...}) -- make a matrix

matrix(Ring,{...}) -- make a matrix

Synopsis:

Function: matrix -- make a matrix

Input:

an instance of class Ring.

an instance of class List.

Output:

an instance of class Matrix.

Optional arguments :

matrix(..., Degree)

matrix(..., DegreeMap)

matrix(R,v) -- create a matrix over R from a doubly-nested list of ring elements or matrices.

This is essentially the same as matrix {...} together with the specification of the ring.

i1 : R = ZZ/101[a..f]



o1 = R



o1 : PolynomialRing

i2 : matrix(R, {{a,b,0},{d,0,f}})



o2 = | a b 0 |

     | d 0 f |
