Aquifer water table timeseries manipulation

I am working with water level time series of wells surrounding Silver Springs, Florida. These wells were installed at different times (anywhere from 60 to 2 years ago), thus I have different timeseries sizes, additionally there are holes in the data which is collected daily (a day here and there missing due to maintenance and such).

Right now I have an array (94948*3) with the measurments from all the wells. My columns are (1)WellID,(2)Julian date of the sampling event (3) depth of the water table.

I have created a string of daily timesteps (daterange=datenum('jan-01-1960'):datenum('october-31-2014'); and a list of wellID's from the 31 wells for which I have data for. The daily string and WellID's would be the rows and columns of the new array I am trying to build.

I need help with how to spatially place (x,y plane) the water table depth records with their respective wellID and date records in the new array.

Thanks- Antonio
