sir i have downloaded ASIFT code from matlab file exchanger. the problem is it showing error sir, please help me to run that code. here i have mentioned errors"Error in mainOrient (line 56) LinearIndOfFPScale_i = sub2ind( [ Nrow, Nclmn ], row, clmn );

Hello Vani,
Seems like Walter has answered your question here:

If this does not help, I would recommend contacting the author of the file exchange submission.
