(22) Types of Matlab Functions

Types of Matlab Functions

• Subfunctions
• contained in m-file of a primary function
• callable only by primary functions and other subfunctions in that file
• does not share workspace of the primary function
• Private Functions
• reside in subdirectory with special name private
• visible only to functions in the parent directory
• useful when overriding another function with the same name
  
• Nested Functions
• defined within the body of another function
• has its own workspace
• has access to the workspace of the function(s)  that it is nested within
• Function Handles
• used in calling functions indirectly
• often used when passing a function name as an input to another function
• handle= @functionname
  
• Anonymous Functions
• simple function which does not require an M-file
• single matlab expression with inputs and outputs
• f = @(arglist) expression
