Hi there,
I have a .txt file that has a list on longitudes and latitudes and I just want to plot the data. I haven't used MATLAB in a few years and so I seem to be coming across an error that I'm sure is simple to fix.
I thought I could just use: importdata('filename.txt') and then plot each column, but when I do that, the following error message is displayed: ??? Error using ==> importdata at 115 Unable to open file.
I checked the data but can't seem to see any reason why it can't import. Any help would be much appreciated?
Many thanks

Please post the relevant parts of your code, and attach part of your text file (or all of it if it’s not too long). Be sure your file is in the MATLAB search path.

Looks like the error that is kicked out when the file isn't there. Check that it is in your work directory or include the full path as the string input to importdata.
