Accepting and saving multiple size matrix input

a=[1];

b=[2 3 4];

c=[5; 6; 7];

d=[8 9 10; 11 12 13; 14 15 16];

I want to make a function that works with an undefined number of inputs.

In this case, 4 inputs (a,b,c,d)

////////////

Then I make the function as follows:

function out=Func(varargin)

Then when I use the function, I input:

result value=Func(a,b,c,d) %Only this command is allowed to get result value. The only changes that can be made are changing the number of input matrices.

////////////

Inside the function when I use the varargin, I get:

varargin(1) % [1]

varargin(2) % [1x3 double]

varargin(3) % [3x1 double]

varargin(4) % [3x3 double]

Is it possible to get the values of b,c,d instead of the matrix sizes?

I want to work with the values of b,c,d.

For example

out= sum(a) + sum(b) + sum(c) + sum(d)

I have a function 'Func'

function out = Func(varargin)
out = 0;
for num = 1 : nargin
    out = out + sum(varargin{num}(:));
end

Save the function with filename 'Func.m' And then I have a m-file

clear all; clc;

a=[1];
b=[2 3 4];
c=[5; 6; 7];
d=[8 9 10; 11 12 13; 14 15 16];
value = Func(a,b,c,d)

Then, try to run your m-file. You will get :

value =

     136

As I understand you want a function undefined number of input. so it can either be implemented as follow.

function myFunc(varargin)

switch nargin
   case{0}
% this mean no argument. 
   case{1}
% means one argument

     case{2} 
  % means two argument. and so on

otherwise
% default 

end
