Problem concatenating a matrix of numbers with a vector of strings (column labels) using cell2mat

Question

I\'m a Mac user (10.6.8) using MATLAB to process calculation results. I output large tables of numbers to .csv files. I then use the .csv files in EXCEL. This all works f

You will have to handle writing the column headers and the numeric data to the file in two different ways. Outputting your cell array of strings will have to be done using the FPRINTF function, as described in this documentation for exporting cell arrays to text files. You can then output your numeric data by appending it to the file (which already contains the column headers) using the function DLMWRITE. Here's an example:

fid = fopen('myfile.csv','w');              %# Open the file
fprintf(fid,'%s,',columnsHeader{1:end-1});  %# Write all but the last label
fprintf(fid,'%s\n',columnsHeader{end});     %# Write the last label and a newline
fclose(fid);                                %# Close the file
dlmwrite('myfile.csv',numbersTable,'-append');  %# Append your numeric data
