tprintf provides an intuitive interface to fprintf for writing tabular data to a text
file. tprintf(filespec,format,A1,...,An) creates a tabular text file by writing the
columns of A1,...,An to columns in the text file.
.
fprintf(fid,format,v1,v2,...), where v1,v2,... are scalars, writes one row. To
print several rows one may put the function in a for-loop. That code is easy to read and
understand. However, with large files speed becomes a problem. fprintf(...,C{:}),
where C is a cell array containing numeric and character data, writes the text file much
faster. With pure numerical data fprintf(...,M), where M is matrix writes even faster.
However, the cell array, C, and the matrix, M, come at a price. It takes some effort to
create them and the resulting code is not all that easy to read and understand - IMO.
With tprintf I try to combined the best of the two.

Installation: This submission consists of three m-files and this documentation. Copy the
m-files to a folder on the Matlab search path. Verify that tprintf is working by running
.
>> tprintf( 1, '%d, %4.1f, %s, %s\n', [1;2], rand(2,1),{'first';'second'},['ABC';'DEF'] )
1, 0.6, first, ABC
2, 0.1, second, DEF
