function in a script file

Can I write a function inside a if statement in a script file?

@PA if you are not able to understand the responses, then please ask for clarification... after restoring the code, so that people will understand the situation you are working with.

Answer 1

[Walter Roberson]

"function" statements can never be inside a flow control statement.

Anonymous functions can be defined inside flow control.

Answer 2

[David Hill]

a=5;b=10;
if b>a
    c=executeFunction(a,b)
end

c = 35

function c=executeFunction(a,b)
  c=b*3+a;
end

[Walter Roberson]

function input = obj.CON_Pattern

The only time that you can use a period as part of a function name for a function definition, is for set and get methods of a classdef

You asked about script files but your code appears to have been written for class methods? (App Designer creates classes, not scripts)

[PA]

yeah its written for class method

[Steven Lord]

If obj is an instance of a class with a method named CON_Pattern you could call the method as obj.CON_Pattern or as CON_Pattern(obj). But you would have to define it as function CON_Pattern(obj).

You cannot define a function inside an if statement.

You can define a function in a script or function file outside of the if statement and call it inside.
