USER-DEFINED FUNCTIONS

There are three types of functions:

• Functions that calculate and return one value.
• Functions that calculate and return multiple values.
• Functions that accomplish some task (e.g. print to screen) without returning any values

RETURNING ONE VALUE

• user-defined function format example (to calculate area):
• help to the function:
• type command to see the script and function:
• multiple inputs:

RETURNING MORE THAN ONE VALUE

• functions [area, circumference] = my_circle(radius)
• calling the function using [a, c] = my_circle(4)
• using vector of inputs in the function:
• calling this function for a single variable for the output:

FUNCTIONS THAT ACCOMPLISH A TASK WITHOUT RETURNING VALUES

• function that print 2 given numbers:
