document {
Key => {genericMatrix, (genericMatrix,Ring,RingElement,ZZ,ZZ), (genericMatrix,Ring,ZZ,ZZ)},
Headline => "make a generic matrix of variables",
Usage => "genericMatrix(R,r,m,n)",
Inputs => {
"R" => Ring,
"r" => RingElement => {"which is a variable in the ring ", TT "R",
" (this input is optional)"},
"m" => ZZ,
"n" => ZZ
},
Outputs => {
Matrix => {"with ", TT "m", " rows and ", TT "n",
" columns whose entries are variables in the ring ", TT "R",
" starting with ", TT "r"}
},
EXAMPLE {
"R = ZZ[a..z];",
"genericMatrix(R,a,2,4)",
"genericMatrix(R,i,3,2)"
},
PARA{},
"Omitting the input ", TT "r", " is the same as having ", TT "r",
" be the first variable in ", TT "R", ".",
