I am trying to do the interpolation between given set of data. I used interp1 function but it is showing the error as ''The grid vectors are not strictly monotonic increasing''
A=
290.21
291.22
291.11
290.73
293.03
299
304.92
323.5

I write the code like this..
x=0.2:0.1:0.5
D=interp1(B,A,x)
How to solve this problem??
Thanks

The code you posted works. What do you want to do with your data and the interpolation? You have to tell us what the problem is.

Hi,
in your file B67 is equal to B68. Remove one of the lines.

No, since the data on x are not monotonic. Now it depends on the application, you can e.g. sort the data (using sort or sortrows), if this makes sense.
