Post subject:  2d_interpolation 
Hi, first of all sorry for bad English.. Recently I've face with problem to interpolate the 2 dimensional data, but they are in the different recording than they need for spline2dbuildbicubic() and spline2dbuildbilinear() methods. For example, I know the spline absciss array[0..N1] (temperature ADC values) and function value array[0..M1,0..N1] (a dependence the ADC pressure values from the temperature). The spline ordinates array[0..M1] (just the physical values of pressure) is a required for. I can get the spline interpolant by spline2dbuildbicubic(), but then how can I calculate the ordinate value? Are there more methods to solve this problems? TIA
