function, endfunction — opens a function definition
function <lhs_arguments>=<function_name><rhs_arguments>
<statements>
endfunction
Where
| <function_name> | stands for the name of the function |
| <rhs_arguments> | stands for the input argument list. It may be |
| - | a comma separated sequence of variable names enclosed in parenthesis, like (x1,...,xm). Last variable name can be the key word varargin (see varargin) |
| - | the sequence () or nothing,if the function has no input argument. |
| <lhs_arguments> | stands for the output argument list. It may be |
| - | a comma separated sequence of variable names enclosed in brackets, like [y1,...,yn]. Last variable name can be the key word varargout (see varargout) |
| - | the sequence [] ,if the function has no input argument. In this case the syntax may also be: function <function_name><rhs_arguments> |
| <statements> | stands for a set of scilab instructions (statements) This syntax may be used to define function (see functions) inline or in a script file (see exec). For compatibility with old Scilab versions, functions defined in a script file containing only function definitions can be "loaded" into Scilab using the getf function. |
The function <lhs_arguments>=<function_name><rhs_arguments> sequence cannot be split over several lines. This sequence can be followed by statements in the same line if a comma of semi column is added at its end.
function definitions can be nested
//inline definition (see function) function [x,y]=myfct(a,b) x=a+b y=a-b endfunction [x,y]=myfct(3,2) //a one line function definition function y=sq(x),y=x^2,endfunction sq(3) //nested functions definition function y=foo(x) a=sin(x) function y=sq(x), y=x^2,endfunction y=sq(a)+1 endfunction foo(%pi/3) // definition in an script file (see exec) exec SCI/macros/elem/asin.sci;
