HP 48gII Graphing, 50g Graphing manual Lcxm, Ldec

Output:	The least common multiple of the objects.
Flags:	Exact mode must be set (flag –105 clear).
	Numeric mode must not be set (flag –3 clear).
	Radians mode must be set (flag –17 set).
Example:	Find the least common multiple of the following two expressions:
	x2 – 1
	x–1
Command:	LCM(X^2-1,X-1)
Results:	X^2-1
See also:	GCD
LCXM
Type:	Command
Description:	From a program with two arguments, builds a matrix with the specified number of rows and
	columns, with aij = f(i,j).
Access:	Catalog, …µ
Input:	Level 3/Argument 1: The number of rows you want in the resulting matrix.
	Level 2/Argument 2: The number of columns you want in the resulting matrix.
	Level 1/Argument 3: A program that uses two arguments. An expression with the two variables I,
	J can be used instead.
Output:	The resulting matrix.
Flags:	Exact mode must be set (flag –105 clear).
	Numeric mode must not be set (flag –3 clear).
Example:	Build a 2 × 3 matrix with aij=i+2j.
Command:	LCXM(2,3,« →I J 'I+2*J'»)

Result:		4 6 8
LDEC
Type:	Command
Description:	Solves a linear differential equation with constant coefficients, or a system of first order linear
	differential equations with constant coefficients.
Access:	Symbolic solve, !Îor PSOLVER or !ÖDIFF
Input:	Level 2/Argument 1: For a single equation, the function forming the right hand side of the
	equation. For a system of equations, an array comprising the terms not containing the dependent
	variables.
	Level 1/Argument 2: For one equation, the auxiliary polynomial. For a system of equations, the
	matrix of coefficients of the dependent variables.
Output:	The solution.
Flags:	Exact mode must be set (flag –105 clear).
	Numeric mode must not be set (flag –3 clear).
	Radians mode must be set (flag –17 set).
Example:	Solve 2sin(x), with the auxiliary polynomial x2+1:
Command:	LDEC(2*SIN(X),X^2+1)
