"Error using griddedInterpolant .The sample points must be finite."

load samplefile.mat
interp_horizontal_radiation = interp1(time_sec,horizontal_radiation,interp_time_sec);

On using interp1 for the data set in mat file samplefile.mat, I get an error saying :

"Error using griddedInterpolant .The sample points must be finite."

All 3 argument inputs to interp1 are column vectors of double values. The double values contained in these vectors are finite. The column vectors are of finite length. I don't understand why this error pops up. Could anyone explain what is going wrong ? Thanks in advance.

>> time_sec(95)

ans =

   NaN

>> horizontal_radiation(95)

ans =

   NaN

My bad! Thank you.
