Most MATLAB functions are overloaded. That means that there are several ways to call them and that MATLAB will “Do The Right Thing” based on the number and types of inputs. As a simple example you can call SUM
sum(M) %this will sum along the columns
sum(M,2) %this will sum along the rows
This video shows how you can implement the same behavior based on using
VARARGIN: VARiable ARGuments IN NARGIN: Number ARGuments IN
I think that the recent introduction of the inputParser object has made things evolve a bit with respect to the nargin approach.
Have you ever thought about creating a video with a demo of inputParser?
i have a doubt in using varargin. if i give this as it is in the calling function, i get “Attempted to execute script varargin as a function”. if i omit varargin, it gives the error as “One or more output arguments not assigned during call to…”. what should i have to do? plz send the answer to my mail soon. thanks in advance
I have a problem.I am making a code using MatLab. This code has some subfunctions.In these subfunctions, sometimes I need to call several numbers of value under one variable name and I want to do this for more than one variable in a subfunction.But I found that one variable can hold only one value. Is there any solution? REply please
Hi,I use a free program to do some tidal analysis.But there are some errors when I run it. Attached is the the beginning of the free program.
After I test ‘error(nargchk(2,inf,nargin))’,
the error informatio shows ‘??? Error using ==> nargin Not a valid M-file.’
Can you help troubleshoot it? Thank you in advance.
options = struct(‘logp’,false); % default options
if ischar(x) && strcmpi(x,’defaults’)
f = options;
function [Sx, alphao, fo] = autossca(x,fs,df,dalpha)
if nargin ~= 4
error(‘Right number of arguments’);
Please help me, im having an error in line 3
