How many cells from each side do you want to average: one or more? How do you want to deal with multiple Inf's in a group? What happens with Inf's that are at the edge of the matrix?

Dear Stephen, thank you for your reply. one cell from each side is enough. but i don't have any idea about your next questions! :(

Use TriScatteredInterp or scatteredInterpolant (newer MATLAB versions). You can pass these vectors of your data points excluding the Inf values, and then they will interpolate new points at the grid locations that you specify.
