TANFITXINT Formulator function
Finds a linear equation of the form Y = a + bX from two columns (vectors), VX and VY.
Usage
TANFITXINT(VX, VY, POS)
The name of any column (vector) listed under Columns
The name of any column (vector) listed under Columns
The row number (index) where the tangent is to be found
Details
Finds a linear equation of the form Y = a + bX from two columns (vectors), VX and VY. This
equation corresponds to a tangent of the curve that is created by plotting the values in VY against the
values in VX. The value at which the tangent is found is specified by the argument POS.
Returns the X intercept of the linear equation (value of -a/b in Y = a + bX).
If a VX or VY value at POS is an invalid number (that is, the value is #REF), the function will not return
a valid result.
Example
VT = TANFITXINT(GATEV, DRAINI, MAXPOS(GM))
