inputname

Input argument name

Syntax

• inputname(argnum)
  

Description

This command can be used only inside the body of a function.

inputname(argnum) returns the workspace variable name corresponding to the argument number argnum. If the input argument has no name (for example, if it is an expression instead of a variable), the inputname command returns the empty string ('').

Examples

Suppose the function myfun.m is defined as:

• function c = myfun(a,b)
  disp(sprintf('First calling variable is "%s".',inputname(1))
  

Then

• x = 5; y = 3; myfun(x,y)
  

produces

• First calling variable is "x".
  

But

• myfun(pi+1,pi-1)
  

produces

• First calling variable is "".
