5.6 Functions
5.6.1 Function definition
Functions are program sections that can be parameterized and called from anywhere in the program.
Function declaration consists of the following parts:
1. Reserved keyword function
2. List of output arguments with their types in square brackets– optional
3. Assignment sign – only if there is some output argument
4. Function name
5. List of input arguments with their types in round brackets. List of input arguments may be empty.
For example,
1
function [int y1, int y2] = func1 (float x1, int x2) This function is named func1, it gets two input
arguments x1 and x2 and returns two output arguments
List of output argument may be empty. In this case 2 and 3items are absent or it can be empty square
brackets. If there is the only output argument it can be without square brackets.
Maximal admissible number of input and output arguments is 16.
