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?

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)

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\%');

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%%');
