InstrumentAccelerometerEstimateParameters

This program estimates calibration parameters for acceleration data given given an optional reference acceleration. Specifically, the program solves the equation \[ \mathbf{a} - \mathbf{a}_\text{ref} = \mathbf{f}(\mathbf{x}) + \mathbf{e} \]for the unknown parameters $\mathbf{x}$, where $\mathbf{a}$ is given in inputfileAccelerometer and $\mathbf{a}_\text{ref}$ is given in inputfileAccelerometerReference. The parametrization of $\mathbf{x}$ can be set via parametrizationAcceleration. Optionally, the empirical covariance functions for the accelerations $\mathbf{a}$ can be estimated by enabling estimateCovarianceFunctions.

The estimated parameters are written to the file outputfileSolution and can be used by InstrumentAccelerometerApplyEstimatedParameters to calibrate accelerometer measurements.
