Function ROW+ takes as argument a matrix, a vector with the same length as

the number of rows in the matrix, and an integer number n representing the

location of a row. Function ROW+ inserts the vector in row n of the matrix.

For example, in ALG mode, we'll insert the second row in matrix A with the

vector [-1,-2,-3], i.e.,

In RPN mode, enter the matrix first, then the vector, and the row number,

before applying function ROW+. The figure below shows the RPN stack

before and after applying function ROW+.

Function ROW-

Function ROW- takes as argument a matrix and an integer number

representing the position of a row in the matrix. The function returns the

original matrix, minus a row, as well as the extracted row shown as a vector.

Here is an example in the ALG mode using the matrix stored in A:

In RPN mode, place the matrix in the stack first, then enter the number

representing a row location before applying function ROW-. The following

figure shows the RPN stack before and after applying function ROW-.
