Claim One:
1. A method of calibrating an uncalibrated output from a first spectrometer relative to an output from a second reference spectrometer, said outputs from said first and second reference spectrometers being a two-dimensional matrix of data, the method comprising the steps of: (a) calculating a first banded diagonal transformation matrix, said first banded diagonal transformation matrix depending upon the output provided by said second reference spectrometer in response to a standard sample and the output provided by said first spectrometer in response to said standard sample; (b) calculating a second banded diagonal transformation matrix, said second banded diagonal transformation matrix depending upon the output provided by said second reference spectrometer in response to said standard sample and the output provided by said first spectrometer in response to said standard sample; and (c) multiplying said first and second banded diagonal transformation matrices with said uncalibrated output from said first spectrometer in response to a subsequent sample to provide a calibrated output.
