So i have a set of matrixes F computed in different points (for each matrix there is associated a pair of points V,q). How do i compute an interpolation which gives me all possible F matrixes for values of (V,q) in a certain range not present in my dataset?

I wish i've been clear in my question, thank you

Use griddedInterpolant or scatteredInterpolant on each matrix element separately depending on whether the point pairs (Vi,qj) for which the matrices are computed are reguarly or irregularly spaced.
