Question

Write a MATLAB userdefined function that calculates the product and the ratio of two variables x and y.

1. if any element in the second input argument is 0, then a warning message must be generated (‘Possible division by 0’)

2. if the user calls the function with one input argument, then the second input argument must be equal to the first one.

3. if the two input argumenta are of different sizes, then a proper error message must be generated with the exception when one or both are scalars.

4. the second output argument (ratio) must not be calculated unless the function is called with two output arguments.

Answer 1

`Hey,

Note: Brother in case of any queries, just comment in box I would be very happy to assist all your queries

clc
clear all
[p,r]=fun([3 2 2],[90 0 0])

function [p,r]=fun(x,y)
if(nargin<2)
y=x;
end
if(sum(y==0)>0)
warning('Possible division by 0');
end
[m1,n1]=size(x);
[m2,n2]=size(y);
if(m1~=m2||n1~=n2)
if(~(isscalar(x)||isscalar(y)))
error('Arguments of different sizes');
end
end
p=x.*y;
if(nargout==2)
r=x./y;
end
end

Kindly revert for any queries

Thanks.
