The (indexed) parameter $R$, which specifies the domain of computation, a commutative ring, must be a Maple table/module which has the following values/exports:

R[`0`] : a constant for the zero of the ring R

R[`1`] : a constant for the (multiplicative) identity of R

R[`+`] : a procedure for adding elements of R (nary)

R[`-`] : a procedure for negating and subtracting elements of R (unary and binary)

R[`*`] : a procedure for multiplying elements of R (binary and commutative)

R[`=`] : a boolean procedure for testing if two elements of R are equal

The parameters $A,B$, and $v,w$ must have compatible dimensions for the addition. Similarly, all Matrices in $\mathrm{lA}$, and all Vectors in $\mathrm{lv}$, must have compatible dimensions, and the number of elements of $\mathrm{lc}$, if given, must match the number of element of $\mathrm{lA}$ or $\mathrm{lv}$, respectively.

If $c,d,\mathrm{lc}$ are omitted, then MatrixAdd and VectorAdd just compute the sum of the matrices or vectors, respectively.
