How to match the values at two different columns in matlab

I have some value like this

        lon lat elevation
        77.75  32.075  5826
        77.75  31.775  5444
        77.85  31.875  5406
        77.6  32.125  5378
        77.7  31.725  5353
        77.65  31.875  5317
        77.55  32.025  5271
        77.65  32.075  5251
        77.6  31.875  5233
        77.5  31.925  5233
        77.6  32.025  5205

And I have two different column of lon and lat where lon and lat are the same as previous but in different order

if true
  % code
end
lon      lat   temperature
77.65  32.075   23
77.6  32.025   45
77.65  31.875   34
77.65  32.075   23
77.75  31.775
.       .     .
.       .     .
.       .     .
.

I want a table like this

         lon    lat    elevation  Temperature
        77.75  32.075  5826        23
        77.75  31.775  5444        45
        77.85  31.875  5406         .
        77.6  32.125  5378         .
        77.7  31.725  5353
        77.65  31.875  5317         .
        77.55  32.025  5271         .
        77.65  32.075  5251         .
        77.6  31.875  5233         .
        77.5  31.925  5233         .
        77.6  32.025  5205         .

If you can store the variables in a table, then you could use the join command.
