formated string in matlab

In MATLAB, you can format strings using the sprintf function or the newer string function. Both functions use the same syntax for formatting the output. Here's an example using sprintf:

main.m
x = 3.1415;
y = 42;
str = sprintf('The value of x is %0.2f and the value of y is %d.', x, y);
disp(str);
105 chars
5 lines

This will output:

main.m
The value of x is 3.14 and the value of y is 42.
49 chars
2 lines

In the format string, %0.2f specifies a float number with 2 decimal places, and %d specifies an integer. The values of x and y are substituted accordingly.

Here's an equivalent example using the string function:

main.m
x = 3.1415;
y = 42;
str = string("The value of x is %.2f and the value of y is %d.", x, y);
disp(str);
103 chars
5 lines

Both sprintf and string function provide many formatting options. For more information, see MATLAB's documentation on sprintf and string.
