Find the attachment consists of two columns. 1st column should be interpolated with 2nd column and 2nd column should be interpolated with 1st column.

Try using interp2, spline or pchip. "interpolate first coloumn with second" ????
Lets see an example. A contains the data over 10 points. If you want to interpolate A on finer intervals (say in interval of 0.1), then code would like like:
A=randi(10,1,10);
interp1((1:10),A,(1:0.01:10))
spline((1:10),A,(1:0.01:10))
pchip((1:10),A,(1:0.01:10))
Above are the three different methods of interpolating linear matrix.
Hope you can relate this simple example with your problem.

First input of interp, spline or pchip must be either decreasing or increasing. Read these ( a , b , c ) documentation for details
