functions

Return information about a function handle

Syntax

f = functions(funhandle)
f = functions(@fun)

Description

f = functions(funhandle) returns, in a MATLAB structure, the function name, type, and filename for the function handle stored in the variable, funhandle. For overloaded functions, it also returns a separate structure identifying the classes and M-files that overload the function.

f = functions(@fun) returns the same information for the function, fun.

Examples

To obtain information on a function handle for the display function,

f = functions(@deblank)
f = 
    function: 'deblank'
        type: 'overloaded'
        file: 'matlabroot\toolbox\matlab\strfun\deblank.m'
     methods: [1x1 struct]

The methods field is a separate structure containing one fieldname for each class that overloads the function. The value of each field is the path and name of the file that defines the method.

f = functions(@display);
f.methods

ans = 

   polynom: '\home\user4\@polynom\display.m'
     inline: 'matlabroot\toolbox\matlab\funfun\@inline\display.m'
    serial: 'matlabroot\toolbox\matlab\iofun\@serial\display.m'
    avifile: 'matlabroot\toolbox\matlab\iofun\@avifile\display.m'
