I am using the writematrix(A,'myData.txt','Delimiter','tab') function to export data to a txt file. I need the delimiter but i also need the txt to start at row 5 to avoid the header. I know that for xls you can add 'Range','A5' to specify where the data starts but how do you do that with a txt file?

Hi, the 'Range' parameter in writematrix only works for excel files. You can read more about how to specify range while writing to an excel file here.
You can do the following to export data to .txt file:
A = magic(8);
numRows = 4;
%skipping first 4 rows
fid = fopen('myData.txt','w');
for i = 1:numRows
fprintf(fid, '%s\n','');
end
%making format specifications
[r,c] = size(A);
s2 = '';
s1 = '%d\t';
for i = 1:c
s2 = strcat(s2,s1);
end
%writing A to myData.txt
for iter = 1:r
s = strcat(s2,'\n');
fprintf(fid,s,A(iter,:));
end
fclose(fid);
