matlab中如何将字符串存入矩阵,我如何写字符串和矩阵到MATLAB中的.txt文件？

I need to write data to a .txt file in MATLAB. I know how to write strings (fprintf) or matrices (dlmwrite), but I need something that can do both of them. I'll give an example below:

str = 'This is the matrix: ' ;

mat1 = [23 46 ; 56 67] ;

%fName

if *fid is valid*

fprintf(fid, '%s\n', str)

fclose(fid)

end

dlmwrite(fName, *emptymatrix*, '-append', 'delimiter', '\t', 'newline','pc')

dlmwrite(fName, mat1, '-append', 'newline', 'pc')

This works okay, but with a problem. The first line of the file is:

This is the matrix: 23,46

Which is not what I want. I want to see:

This is the matrix:

23 46

56 67

How can I solve this? I can't use a for loop and printf solution as the data is huge and time is an issue.

I think all you have to do to fix your problem is add a carriage r
