To compare two matrices using the relational operations = and ƒ
(TEST menu), they must have the same dimensions. = and ƒ
compare matrixA and matrixB on an element-by-element basis.
The other relational operations are not valid with matrices.
matrixA
=matrixB returns 1 if every comparison is true; it returns
0 if any comparison is false.
matrixAƒmatrixB returns 1 if at least one comparison is false; it
returns
0 if no comparison is false.
iPart( (integer part), fPart( (fractional part), and int( (greatest
integer) are on the
MATH NUM menu.
iPart( returns a matrix containing the integer part of each
element of matrix.
fPart( returns a matrix containing the fractional part of each
element of matrix.
int( returns a matrix containing the greatest integer of each
element of matrix.
