Returns a column (vector) VY that consists of moving summation of a column (vector) V.
th
The n value in VY (Y ) is the sum of the n

The following example illustrates the SUMMV function numerically:
V VY = SUMMV(V)
1.0000 1.0000
2.0000 3.0000
3.0000 6.0000
4.0000 10.0000

SUMMV(V)
Where: V = The name of any column (vector) listed under Columns.
F1 = SUMMV(BASEI)
PSISPSIO = SUMMV((1-CQADJ/COX)*DELTA(VGS))*DOPETYPE
Returns the tangent of each value in a designated column (vector) under Columns or
any operand.
TAN(X)
Where: X = The name of any column (vector) listed under Columns or any operand.
F1 = TAN(DRAINI)
Returns the value in radians.
Performs the following:
• 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.
