I am trying to calculate the FFT for a data set which has irregular axis and i am getting the following Errors.
yes? use outputp_pottmp.nc
yes? LET fft_td20_full = FFTA(pottmp[z=@loc:20,t=1-jan-2011:31-dec-2011@FLN:1])yes? LET FFT_nf_full = `fft_td20_full,return=lend`
Bailing out of external function "ffta":
Time axis must be a regular axis
**ERROR: error in external function
please help me with this...
