I'm getting a really strange error when trying to use readmatrix() to load a .csv file. It tells me there's not enough input arguments!
d_obs = readmatrix(sprintf('%s/%s',NMR_path,NMR_obs_filename));
this is the command I'm using. The strange thing is that just last week, this worked perfectly, and I have not changed anything since then. If it is at all related, I also get a message "The import tool doesn't have access to read the file" when I try to open the file directly by double-clicking it in the current folder tab. I checked the files and they're not empty.
Anyone got some idea of what is going on here?
