columnMult -- multiply a column by a ring element

Synopsis

Usage:
columnMult(m,i,a)
Inputs:
- m, a mutable matrix
- i, an integer
- a, a ring element, in the same ring as m
Consequences:
- The i th column of m is modified by multiplying it by a

Description

i1 : R = ZZ[a..f]

o1 = R

o1 : PolynomialRing

i2 : m = mutableMatrix genericMatrix(R,a,2,3)

o2 = | a c e |
     | b d f |

o2 : MutableMatrix

i3 : columnMult(m,0,c)

o3 = | ac c e |
     | bc d f |

o3 : MutableMatrix

i4 : m

o4 = | ac c e |
     | bc d f |

o4 : MutableMatrix
