HP Prime Graphing NW280AAABA manual Examples, MaxnormVect or Mtrx, Maxnorm 1 2 3 -4 returns

Max Norm Returns the l∞ norm (the maximum of the absolute values of the coordinates) of a vector.

maxnorm(Vect or Mtrx)

Example:

maxnorm ( 1 2 3 –4 ) returns 4

Examples

Identity Matrix	You can create an identity matrix with the IDENMAT
	function. For example, IDENMAT(2) creates the 2×2
	identity matrix [[1,0],[0,1]].
	You can also create an identity matrix using the MAKEMAT
	(make matrix) function. For example, entering
	MAKEMAT(I ≠ J,4,4) creates a 4 × 4 matrix showing the
	numeral 1 for all elements except zeros on the diagonal.
	The logical operator (≠) returns 0 when I (the row number)
	and J (the column number) are equal, and returns 1 when
	they are not equal. (You can insert ≠ by choosing it from
	the relations palette: Sv.)
Transposing a	The TRN function swaps the row–column and column–row
Matrix	elements of a matrix. For instance, element 1,2 (row 1,
	column 2) is swapped with element 2,1; element 2,3 is
	swapped with element 3,2; and so on.
	For example, TRN([[1,2],[3,4]]) creates the matrix
	[[1,3],[2,4]].
