Using Mathematical Functions with Vectors
vectorA + vectorB Adds each vectorA element to the corresponding vectorB element;
returns a vector of the sums
vectorA NvectorB Subtracts each vectorB element from the corresponding vectorA
element; returns a vector of the differences
vector¹number or
number¹vector
Returns a vector that is the product of a real or complex number times
each element in a real or complex vector
matrix¹vector Returns a vector that is the product of each vector element times each
matrix
element; matrix column dimension and vector dimension must be
equal
vector ànumber Returns a vector that is the quotient of each real or complex vector
element divided by a real or complex number
Mvector (negation) Changes the sign of each vector element
vectorA == vectorB Returns 1 if every corresponding element comparison is true; returns 0
if any is false
vectorA ƒvectorB Returns 1 if at least one corresponding element comparison is false
round( vector [ , #ofDecimals ] ) Rounds each vector element to 12 digits, or rounds to specified
#ofDecimals
iPart vector Returns the integer part of each real or complex vector element
fPart vector Returns the fractional part of each real or complex vector element
int vector Returns the greatest integer of each real or complex vector element
To add or subtract two vectors,
the dimension of
vectorA must
equal the dimension of
vectorB .
You cannot multiply two
vectors or divide one vector
by another vector.
== and ƒ are on the TEST
menu.
round , iPart, fPart, and int
are on the MATH NUM menu.
