inputname
Input argument name
inputname(argnum
)
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 (''
).
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 "".
nargin, nargout
