Ivt.DataCol()

Type: INSTANCE FUNCTION

Purpose: Creates and returns an object of the class DATACOL.

The object is filed with data extracted from one column of the IVT object‘s data array. The data, once extracted, can then be submitted to other objects for further calculation. For example, a LINFIT object performs a linear-regression analysis on two DATACOL objects.

A new DATACOL object is automatically created by the call to IVT.DataCol(). It is usually transient, existing only for one function call.

Usage: DataCol = Ivt.DataCol(ColumnCode)

DataCol

DATACOL

The new object containing the data
extracted from the IVT data array.

ColumnCode

INDEX

A code identifying the column to be
used. Use these predefined constants :

IVT_T = Time

IVT_Vf = Applied voltage

IVT_Vu = Uncompensated voltage

IVT_Im = Measured current

IVT_Am = Measured voltage Aux Channel

IVT_Sig = Signal sent to control amplifier
