create Two dimensional Using NationalInstruments.ComplexDouble.ComposeArray

[majumdar.sujoy]

Dim InpDataX(3, 1) As Double

InpDataX(1, 0) = 10.1

InpDataX(1, 1) = 20.1

Dim InpDataY(3, 1) As Double

InpDataY(1, 0) = 10.1

InpDataY(1, 1) = 20.1

Dim ydata(3, 1) As NationalInstruments.ComplexDouble

ydata = NationalInstruments.ComplexDouble.ComposeArray(InpDataX(), InpDataY())

The above line is giving error .I intend to create a two dimensional complex number.Please help
