When system flag 117 is set to SOFT menus, the ROW menu is accessible 
through 
„´!)MATRX !)@@ROW@ , or through „Ø!)@CREAT@ !)@@ROW@ .  Both 
approaches will show the same set of functions:
The operation of these functions is presented below.
Function 
ROW
Function 
ROW takes as argument a matrix and decomposes it into vectors 
corresponding to its rows.  An application of function 
ROW in ALG mode is 
shown below.  The matrix used has been stored earlier in variable A.  The 
matrix is shown in the figure to the left. The figure to the right shows the matrix 
decomposed in rows.  To see the full result, use the line editor (triggered by 
pressing 
˜).
     
In RPN mode, you need to list the matrix in the stack, and the activate function 
ROW, i.e., @@@A@@@ ROW.  The figure below shows the RPN stack before and 
after the application of function 
ROW.
     
In this result, the first row occupies the highest stack level after decomposition, 
and stack level 1 is occupied by the number of rows of the original matrix.  The
