Gas concentration, pressure and temperature distributions determining method for use in e.g. motor vehicle, involves providing cubic polynomial as interpolating function, where interpolating function and mixed derivations are same
The method involves approximating functions by interpolated, two dimensional, cubic spline functions. A desired pressure and temperature range is divided into rectangular sub-ranges and a two-dimensional cubic polynomial is provided as interpolating function, where derivations of the interpolating function based on the pressure and temperature and the mixed derivations based on the pressure and temperature are the same.
