Given a matrix and two integers, returns the matrix obtained

from the given matrix after the row indicated by the second

integer is replaced by the sum of the rows indicated by the

two integers.

rowAdd(Matrix, Integer1, Integer2)

Example:

rowAdd

returns

rowDim

Returns the number of rows of a matrix.

rowDim(Matrix)

Example:

rowDim

gives

2

rowSwap

Given a matrix and two integers, returns the matrix obtained

from the given matrix after swapping the two rows indicated

by the two integers.

rowSwap(Matrix,Integer1,Integer2)

Example:

rowSwap

returns

rsolve

Given an expression defining a recurrence relation, a

variable, and an initial condition, returns the closed form

solution (if possible) of the recurrent sequence. Given three

lists, each containing multiple items of the above nature,

solves the system of recurrent sequences.

rsolve(Expr, Var, Condition) or rsolve(List1,
List2, List3)

Example:

rsolve(u(n+1)=2*u(n)+n,u(n),u(0)=1) returns
[-n+2*2
