dear rajesh
I want to get the wavenumber as well as frequency spectrum, In matlab one can do that using fft2 function. But when using a neccdf file it encounters NAN values that need to be avoided. Iam new to matlab, any suggesitions to get around this
cheers

Dear Nuncio,
Sorry that i did not reply your post till date.
I thought you were trying to do fft for a single time series. If so, you can do it by converting it to an ascii file. If it is spatial, it is difficult and i did it in grads using netcdf data. I have not done fft in matlab for a netcdf data.
regards,
