Image out of sfit

Hi all,

I want to extract an image( uint of float matrix) out of sfit object, because method imshow and some other useful methods, are not defined for sfit data type.

thanks, Nikola

I don't know what an sfit object is. If it's in a MATLAB axes as a plot or image of some kind, then maybe you can use getframe().

An sfit object encapsulates the result of fitting a surface to data. They are normally constructed by calling the FIT function.

 sfit methods:
        coeffvalues   - Coefficient values.
        confint       - Confidence intervals for the coefficients of a fit
                        result object.
        differentiate - Differentiate a surface fit object.
        feval         - FEVAL an sfit object.
        plot          - Plot a surface fit object.
        predint       - Prediction intervals for a fit result object or new 
                        observations.
        probvalues    - Problem parameter values.
        quad2d        - Numerically integrate a surface fit object.
