Neel, did you call the function with proper input arguments, such as

 >> rec = interpolation([1;2],3,1)  % I am just making up numbers here

With this function call n=2.

[Neel]

no

did you run it as script?? you need to call the function and pass on the input varaible. Go through this documentation:
