Answer 1

In MATLAB fprintf function, % represents a format specifier or rule for outputting an argument.

Step-by-step explanation:

In a MATLAB fprintf function, the % symbol is a format specifier or rule for outputting an argument. It is used to define the type and format of the data that will be printed. When using the fprintf function, you can include % followed by a letter or a sequence of letters that represent different data types. For example, %d is used for integers, %f for floating-point numbers, and %s for strings.

Here is an example:

fprintf('The value of x is %d and the value of y is %f.', x, y);

In this example, %d and %f are format specifiers that will be replaced with the values of x and y, respectively.
