How to fprintf with

I want to fprintf to a text file a cell with contents '\begin{table}' the problem is it doesn't work because matlab thinks \b is a control character. How to do this?

What version of MATLAB are you using? Can you give an example of what you have tried.

On 2014a, this simple example works OK....

T = {'\begin{Table}'}
fout=fopen('Test_File.dat', 'wt');
fprintf(fout, '%s\n', T{:});

And the output file contains

\begin{Table}

Simply using

fprintf(fout, '%s\n', '\begin{Table}');

Also gives the same result

Thankyou, the %s\n works. If you repost as an answer I can accept it (otherwise I don't think you get any credit).

Expanding my comment above to add in some LaTex specific requirements, here is a basic working example

% Define some data  
T = [{'Header1'}, {'Header2'}, {'Header3'}; {1.234343}, {32.131234}, {85.23401}; {0.1123}, {0.12213}, {4}];

fout=fopen('Test_File.dat', 'wt');
fprintf(fout, '%s\n', '\begin{table}'); % start the table
fprintf(fout, '%s & %s & %s \\\\\n', T{1,:}); % print the header
fprintf(fout, '%2.3f & %2.3f & %2.3f \\\\\n', T{2:end,:}); % print the data
fprintf(fout, '%s', '\end{table}'); % end the table
fclose(fout)

Thanks for the example. I use the matlab-data-to-latex-table package, to get the correctly formatted latex table as a Nx1 cell, then it's just

      for i = 1:N 
          fprintf(fileID, '%s\n',latex_table{i}); 
      end

to print to file.

The easiest solution is to supply the string as an argument, and not define it in the format string itself, then you do not need to escape any characters at all because characters in argument arrays are interpreted literally:

fprintf(fid, '%s', '\begin{table}The student scored 82.3\%');

You could even do something neat like this, which provides a newline but without changing the input string:

fprintf(fid, '%s\n', '\begin{table}The student scored 82.3\%');

[Walter Roberson]

If you must code the '\begin{table}' in the format specification instead of in the data like Grieg shows, then you need to use two \ for each place you want a single \ in output.

fprintf(fid, '\\begin{table}')

You also need to use %% to represent any % characters that must appear literally, such as

fprintf(fid, '\\begin{table}The student scored 82.3%%');

[Greig]

Since I assume they are writing a table to LaTeX, to fit the LaTeX syntax they will need to throw in an extra '\\' so that the % sign appears correctly in the final table

fprintf(fid, '\\begin{table}The student scored 82.3\\%%');

There are a couple of functions on the FileExchange for formatting MATLAB output to LaTeX. They maybe useful, but I have never tried them

I am using this one which is the best I've found, but I had to modify it for non-numeric data: https://au.mathworks.com/matlabcentral/fileexchange/44274-converting-matlab-data-to-latex-table
