fprintf and disp %n %d in matlab

To print formatted output in Matlab, you can use the fprintf function. This function allows you to print values with specific formatting, similar to the printf function in other programming languages.

To print an integer value, you can use the %d format specifier. Here's an example:

main.m
x = 42;
fprintf('The answer is %d\n', x);
42 chars
3 lines

This will output:

main.m
The answer is 42
17 chars
2 lines

To print a newline character, you can use the escape sequence \n.

If you simply want to display the value of a variable in the console without any formatting, you can use the disp function. Here's an example:

main.m
y = 3.14159;
disp(y);
22 chars
3 lines

This will output:

main.m
    3.1416
11 chars
2 lines

The value is displayed with the default precision, which is 4 decimal places.

Note that the %n format specifier is not supported in Matlab's implementation of fprintf.
