How to get the input variable names of a function (as cell array)
显示 更早的评论
Hi
this may be a stupid question.
I have a function and I would like to have the input variable names as a strings or cell arrays.
e.g.
I have a function:
function [name, data]=calc_torque(test#,motor1,motor2,engine1,engine2)
[name, data]=calc_torque(test#,varargin)
Within the function I do some calculations and I would also like to get a cell array of the input variable names:
name={'motor1', 'motor2',...}
I tried to do it with inputname(argument) but it only accepts a scalar as argument, So I would only get one name instead of an array of all.
Any help is apprecated
Thanks in advance

It's extremely difficult to see why you would want to do this. If you can explain your reason (i.e. the purpose of the function) it may be that there is some much better approach that avoids getting the variable names.

name = cell(nargin,1);
for K = 1 : nargin
name{K} = inputname(K);
end

It might be more secure and flexible, if you define the input as a STRUCT. Then the wanted names are the fieldnames.

I know of no way to do this with varargin. If it's really important you could pass in a cell array of names as another input.
