INTEG Formulator function
From two columns (vectors)
VX
and
VY
, each one containing
N
values, the
INTEG
function returns a third column
(vector) containing a series of numerical integrals
A
n
, where
n
= 1, 2, ..., N-1, N.
Usage
INTEG(
VX
,
VY
)
VX
The name of any column (vector) listed under
Columns
VY
The name of any column (vector) listed under
Columns
Details
Each integral approximates the area under the parametric curve created by plotting the first
n
values
in
VY
against the first
n
values in
VX
. For
n
= 1,
A
n
= 0. For all other values of
n
, each integral
A
n
corresponds to the following relationship:
For example, for the curve below,
INTEG
returns a column (vector) containing
A
1
equal to 0 (zero
area at the start of a curve, at
X
1
) and
A
2
,
A
3
,
A
4
, and
A
5
equal to curve areas, as shown in the
following graphics.
