I have a data attached as rd.txt file. In the file 1st column represent time data and all other columns are distance data. I want to change 1st column data with time step of 0.02 like 0.02, 0.04, 0.06.....60 sec instead of 0.001,0.002,...60.001 as in rd.txt data. I used interp1 function but it gives me error as Error using griddedInterpolant The grid vectors are not strictly monotonic increasing.
Error in interp1 (line 186) F = griddedInterpolant(X,V,method);
Could anybody face such problem and now how to solve the problem? your answer are highly appreciated. Thank you
