.asc is used for:

• actionscript
• autodesk
• PGP ASCII Armored File
• LTspice Circuit Schematic
• ArcGrid and ESRI Grid GPS files
• Adobe Flash
• Atlantis Spellchecker
• WinAmp media file

I do not believe it is legally possible to write code that can read all of those, as I believe that at least two of those are proprietary formats. Also, the concept of "row" and "column" is difficult to apply to some of those files.

I think you are going to have a difficult time writing code to meet the given requirements.

fid = fopen('new.asc', 'rt');
C = textscan(fid, '%s%s%f%f', 'Delimiter',',', 'HeaderLines', 1);
fclose(fid);

Now, column #K is C{K} and row #J of column #K is C{K}{J} for column 1 or column 2 (the strings) or C{K}(J) for column 3 or column 4 (the numbers).

col1 = C{1};
col2 = C{2};
col3 = C{3};
col4 = C{4};

col4(17)  %row 17 column 4
