MATLAB: How to read a string

%ssscanf

hello there,

I am very tired and I would need to read a string like this

tline = 'CHTRS95 46.521464753 6.567893633 460.487'

tline is a char, I want to put the first word in a string and the three numbers in a double.

All using this function:

sscanf(tline, ' %f %f')

(it is somehow wrong,

I get :"

Unable to perform assignment because the size of the left side is 1-by-2 and the
size of the right side is 0-by-0

.")

split = textscan(tline, '%s%f%f%f');
txt = split{1}
numbers = cell2mat(split(2:end))

Hi,

you need to tell textscan, that a space (" ") doesn't split strings. Add this to the call of textscan:

C = textscan(fileID,'%f,%f,%f,%f,%f,%f,%f,%f,%f,%f,%f,%f,%s', 'delimiter', '\n')

This says that only read new data again after a new line (and not start after the first word of the string at the end).

I bypassed this problem by using a different command to read the text file.

using the code:

      vVolumeFaceMx(:,volumeCounter) = sscanf(tline, '%x %x %x %x %x');
      tline = fgetl(fid_source);
      volumeCounter = volumeCounter+1;

allowed me to read it into a hexadecimal format to begin with.
