InSAR3Ddisp.m
This routine takes up 3 to more displacement inputs to resolve the 3D displacement field pixel-by-pixel given the correct parameters of satellite geometry. The output is not only the inverted result but also the type of inputs that were taken into the inversion for a specific pixel.
The azimuth displacement is recorded in the first digit whereas the LOS displacement is stored in the second digit. An example can be seen as follow.

Convert2Grd.m
This routine lets you convert your MatLab result back to GMT grid format (netCDF). After running this, you will acquire one .txt file and a csh file (XYZ2GRD.csh). Go to this working directory in terminal and run csh XYZ2GRD.csh.
