fprintf to print to both file and command window

I'd like to run a single fprintf operation to print to both command window and file.

I know that the below command only print to 'log.txt' file:

fid = fopen('log.txt', 'w');
fprintf(fid, 'start logging\n');

And below will only print to command window:

fprintf('start logging\n');

Is there a way to print to both without calling fprintf twice?

Thanks,

I doubt it.

I'm not sure what your goal is, but it would certainly be trivial to write your own small function. Something like

function [] = writeToScreenAndFile(fid,str)
    fprintf(fid, str);
    fprintf(str);
end

The goal is to have a log file which logs desired stutus messages. However, I also would like the log messages to appear on the command window as well.

Read my answer here: https://www.mathworks.com/matlabcentral/answers/516548-using-fprintf-to-write-to-multiple-files-simultaneously#answer_424960 which answers this exact question. It suggests two methods: create a custom function or overloading fprintf function.
