Hi there,

So I have a space separated text file and im trying to alter this piece of code "tmp=textscan(tmpl,'%s %s %s %s %s')" so that matlab only reads "4.259" and not "4.259M"

 11- Number yyyy mm dd hh mi ssf         f          f 
 12-     1) 2017/01/01 00:00:00     4.259M     0.053M

Code:

 function data=load_tide_data(filename)
 data.filename=filename;
 fid=fopen(filename);
 for I=1:12
    tmpl=fgetl(fid);
end
 J=1;
while ischar(tmpl)
    tmp=textscan(tmpl,'%s %s %s %s %s');
 data.t(J)=datenum([ cell2mat(tmp{2}) ' ' cell2mat(tmp{3}) ]);
    tmph=str2num(cell2mat(tmp{4}));
    if isempty(tmph)
        tmph=NaN;
    end
    data.h(J)=tmph;
    tmpl=fgetl(fid);
    J=J+1;
end

fclose(fid)

Any ideas would be greatly appreciated :)

An ugly solution would be to add M as a delimiter and use multipledelimsasone, the downside being that it would interpret all letters M as delimiters..
