1951 Proc. IRE 39 1158/2 All that is required is the addition (or subtraction..) of fractions of the camera currents to derive the currents required to control the receiver. [Note] This operation has been called ‘matrixing’ in some discussions. The analogy to the matrix operation, which is used in vector algebra to change from one system of co-ordinates to a second, is obvious.
1955 J. W. Wentworth Color Television Engin. iv. 125 Matrixing can be used to improve color fidelity only when camera signals are produced by linear devices.
1971 D. J. Seal Mazda Bk. Pal Receiver Servicing v. 89 Since the luminance signal (−Y) is applied to all three cathodes, the tube performs the final matrixing, and the three gun currents are proportional to the original red, green and blue separation signals from the colour cameras.
