I am trying to create a grid from column data. I have 3 columns, an X coordinate, a Y coordinate, and a column of values (in this case salinity) measured at the X Y locations. I want to turn this data into a grid and then create a countour plot. I can do the plotting bit but I can't find a simple way of transforming the column data to gridded data. I am a little new to Matlab and any help would be greatly appreciated.

Try TriScatteredInterp().

Thanks for that. I used the Triscatteredinterp, created a meshgrid and then interpolated my data over that meshgrid. Works fine. However, if I had wanted to turn my three columns of data into a grid from the start, what would be a good function to use ?
