Anyone knows how to use multiple format in fprintf?

I normally assign the format to fprintf individually e.g.,

fprintf('%3.0f %3.0f %3.0f %3.0f',[10 10 10 10]);

But what if I would like to assign the format only once like:

fprintf('4*%3.0f',[10 10 10 10]);

(it does not work this way, just for an example)

Is there any way I can do this?

Thank you

No. However, you can use

ncol = 4;
fmt = [repmat('%3.0f ', 1, ncol - 1), '%3.0f\n'];
fprintf(fmt, [10 10 10 10]);

Or if you really do not want the newline:

fmt = repmat('%3.0f ', 1, ncol);
fmt(end) = [];  %remove trailing space
fprintf(fmt, [10 10 10 10]);
