genericMatrix -- make a generic matrix of variables

Synopsis

Description

i1 : R = ZZ[a..z];
i2 : genericMatrix(R,a,2,4)

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

             2      4
o2 : Matrix R  <-- R
i3 : genericMatrix(R,i,3,2)

o3 = | i l |
     | j m |
     | k n |

             3      2
o3 : Matrix R  <-- R

Omitting the input r is the same as having r be the first variable in R.
i4 : genericMatrix(R,2,4)

o4 = | a c e g |
     | b d f h |

             2      4
o4 : Matrix R  <-- R
i5 : genericMatrix(R,3,2)

o5 = | a d |
     | b e |
     | c f |

             3      2
o5 : Matrix R  <-- R
