matrix does not survive decomposition, i.e., it is no longer available in the

stack.

Function ROW→

Function ROW→ has the opposite effect of the function →ROW, i.e., given n

vectors of the same length, and the number n, function ROW builds a matrix

by placing the input vectors as rows of the resulting matrix. Here is an example

in ALG mode. The command used was:

ROW([1,2,3],[4,5,6],[7,8,9],3)

In RPN mode, place the n vectors in stack levels n+1, n, n-1,…,2, and the

number n in stack level 1. With this set up, function ROW places the vectors

as rows in the resulting matrix. The following figure shows the RPN stack before

and after using function ROW.

Function ROW+

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+.
