 MatrixAdd
 add two matrices
 VectorAdd
 add two vectors

 Calling Sequence MatrixAdd[R](A,B,c,d) VectorAdd[R](v,w,c,d) MatrixAdd[R](lA,lc) VectorAdd[R](lv,lc)

Parameters

 R - the domain of computation A,B - Matrices of values in $R$ c,d - (optional) scalar values in $R$ (default values: $1$) v,w - Vectors of values in $R$ lA - non-empty list of Matrices over $R$ lc - (optional) non-empty list of scalar values in $R$ lv - non-empty list of vectors over $R$

Description

 • 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.
