Question

This is a code in MATLAB

THE HALCYON DAYS OF ERROR-CHECKING IN ENGR 2060 As usual, turn in your Matlab function & script for Problem #1. 1) Write a function that will accept an arbitrary number of input arguments (where the input arguments are n x m real- valued, numerical arrays, where 1 n<oo and 1Srn<㏄). This function will return two values: the number of input arguments given by the user, and b. a. the sum of all the elements of all the arrays. e.g. ifa-1 2; 341, b= [3 4 5; 6 7 81, and c=[1 1 1 1:1 1 1 1:1 1 1 1], then you would call the function (named "foo" below) as follows (with proper response shown): >> [one, two]-foo(a,b,c) one or >>[one, two]=foo (b,c) one: two 45

Answer 1

% Matlab function that accepts variable length inputs and returns the
% number of inputs in variable one and the sum of all elements of the
% arrays in variable two
function [one,two] = foo(varargin)
one = nargin; % number of inputs to the function
two = 0;
% loop to calculate the sum of elements in input arrays
for i=1:nargin
for j = 1:size(varargin{i},1)
for k=1:size(varargin{i},2)
two = two + varargin{i}(j,k);
end
end
end
end

%end of function
