=== Data acquisition and control systems === In [[data acquisition]] and [[control system]]s, lookup tables are commonly used to undertake the following operations in: * The application of [[calibration]] data, so as to apply corrections to uncalibrated measurement or [[setpoint (control system)|setpoint]] values; and * Undertaking [[measurement unit]] conversion; and * Performing generic user-defined computations. In some systems, [[polynomial]]s may also be defined in place of lookup tables for these calculations.
