Perhaps any of you has been dealing with this issue that has stopped me
for some time. I have built a spline approximation to an image, thus giving me a surface representation. I must do operations with this spline-approximated image and its gradient (sum, prod), in order to integrate them after. This seems a troublesome issue. * I can not "build" a symbolic version of the ppform (or of the B-form) of this image and its gradient in order to be able to integrate through symbolic. Is this possible, or I should forget about doing so? * I can not sum or multiply two splines in ppform (fncmb only works for univariate functions, except for the case when there is just one function in the input). Any idea about this way? Please can anybody help?!
