SPLINE-INTERPOLATOR Russian patent published in 1999 - IPC

Abstract RU 2140099 C1

FIELD: automatic control and computer engineering. SUBSTANCE: device has three memory units, four multipliers, adder, register, control unit, counter, fast Fourier transform unit, fast inverse Fourier transform unit, and spline parameter generating unit. Desired precision of interpolation is attained due to considering a priory information about smoothness of function and using entire array of function samples. EFFECT: improved precision of interpolation in computing functions incorporating continuous fourth derivative. 2 cl, 6 dwg
