What is the usage of the format function in Matlab?

In MATLAB, the format is used to control the output format. It can be set to several modes as follows:

1. Short format: Display floating-point numbers in the default way, showing 4 decimal places.
2. Show floating-point numbers with 15 digits after the decimal point in the default format.
3. Display floating point numbers in scientific notation with 4 decimal places.
4. Display floating-point numbers in scientific notation with 15 digits after the decimal point: format long e.
5. Display floating point numbers in currency format, showing two decimal places and using commas to separate thousands.
6. Format+: Display a plus sign before positive numbers.
7. compact format: remove any empty lines and spaces in the output.
8. Keep any empty lines and spaces in the output format.

The formats can be applied to MATLAB’s output using the format command to control the style of the output format.
