Replace inf by nan and use inpaint_nans by John D'Errico or Inpaint over missing data in 1-D, 2-D, 3-D,... N-D arrays by Damien Garcia

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.
