在 MATLAB Online 中打开

fprintf(F_ID, '%1.1f %1.1f\n', X)

where X has two columns. X is the variable in the MATLAB workspace contain the numbers.

Or

fprintf(F_ID, '%1.1f %1.1f\n', a,b)

where a = 1.0 and b = 2.0

In regards to your question "What is the syntax of fprintf? Suppose there are two flot numbers 1 and 2, and F_ID is the file identifier. Write the command to sabe the two numbers to F_ID?"

fprintf(F_ID, '%f, %f\n', number1, number2);

That will put them on their own line, separated by a comma. If you want a certain number of decimal places, say 3, then do it like this:

fprintf(F_ID, '%.3f, %.3f\n', number1, number2);
