HP 50g Graphing, 48gII Graphing manual Rswp, Rules, Det, Idn, Cswp, Row+, Row, Access … Ã R → B

•B and Z must both be vectors or both be matrices.

•B and Z must have the same number of columns if they are matrices.

RSD is typically used for computing a correction to Z, where Z has been obtained as an approximation to the solution X to the system of equations AX = B.

Access:	!Ø OPERATIONS LRSD		( Ø is the leftshift of the			5key).
	!´MATRIX LRSD		( ´is the leftshift of the Pkey).
Input/Output:
		Level 3/Argument 1	Level 2/Argument 2	Level 1/Argument 3		Level 1/Item 1
		[ vector ]B	[[ matrix ]]A	[ vector ]Z	→	[ vector ]B–AZ
		[[ matrix ]]B	[[ matrix ]]A	[[ matrix ]]Z	→	[[ matrix ]]B–AZ

RSWP	Command
Type:
Description:	Row Swap Command: Swaps rows i and j of a matrix and returns the modified matrix, or swaps
	elements i and j of a vector and returns the modified vector.

Row numbers are rounded to the nearest integer. Vector arguments are treated as column vectors.

Access:	!ØCREATE ROW LRSWP		( Ø is the leftshift of the			5key).
	!´MATRIX ROW LRSWP		( ´is the leftshift of the Pkey).
Input/Output:
		Level 3/Argument 1 Level 2/Argument 2		Level 1/Argument 3		Level 1/Item 1
		[[ matrix ]]1	nrow i	nrow j	→	[[ matrix ]]2
		[ vector ]1	nelement i	nelement j	→	[ vector ]2

RULES	Command
Type:
Description:	Displays a list of names of individuals involved with the HP 49G calculator project.
Access:	…µRULES
Input/Output:	None
R→B	Command
Type:

Description: Real to Binary Command: Converts a positive real to its binary integer equivalent.

For any value of n ≤ 0, the result is # 0. For any value of n ≥ 1.84467440738E19 (base 10), the result is # FFFFFFFFFFFFFFFF (base 16).

Access: …ÃR→B (Ã is the rightshift of the 3key).

Flags: Binary Integer Wordsize (–5 through –10), Binary Integer Base (–11, –12)
