Re: Using otpiminterp in octave

[Zilore Mumba]

The data I used is as in the attached file

Just to be sure I read in the data as per lines below:

% load the data file
data=""

% the 1st and 2nd column represent the location
x = data(:,1);
y = data(:,2);
% the 3rd column represents the observations to interpolate
obs = data(:,3);

The output I get has no similarity with the input. Am not sure if am printing the error field.

I have just installed octave on ubuntu. Trying the example "example_optiminterp_data.m" with my own data, I get very strange values (very small values) see extract of output below

Here is the line I added for the output
save mydata.txt fi;

suspect am not printing the correct results.
I apologise for this very basic question
Help will be appreciated
