#### Description

The following example will define a user function, makePlural, that will take an argument (which is a Matrix value). The mapc function then applies each Matrix value as argument to the function makePlural.

#### Details

Define a Matrix containing various fruit names:

 (define Fruits #(mat| "apple" "orange" "lemon") ) Returns: #

Define a function that takes a single Matrix argument and converts each Matrix member to plural.

 (defun makePlural (V) (append V "s")) Returns: #

Convert each of the fruits to the plural form:

 (setq many (mapc makePlural Fruits) ) Returns: lemons
