Question

Write a function with the header:

               function [out] = myDataTypeChecker(A,B)

takes two matrices A and B and has the following behavior (in this order):

1. 1) if either A or B contains a “Not a Number”, the function should return -1.

2. 2) if either A or B contains an +/-Infinity, the function should return -2

3. 3) if either A or B is a character array, the function should return -3

4. 4) if both A and B are logical arrays, the function should check to see if A and B

   are the same size.

   1. If they are not, it should return -4

   2. If they are, it should return the AND of A and B (an array indicating where

      both A and B are true)

5. 5) if both A and B are numeric arrays, the function should check to see if A and B

   are the same size.

   1. If they are not, it should return -5

   2. If they are, it should return an array of the absolute value of the difference

      of A and B.

6. 6) If A and B are not both logical arrays or not both numeric arrays,, it should return

   -6;

Answer 1

function [ out ] = myDataTypeChecker( A,B )
%UNTITLED2 Summary of this function goes here
% Detailed explanation goes here
  
lenA = length(A);
lenB = length(B);
for i=1:1:lenA
if(isnan(A(i)))
out = -1;
return
end
end
  
for i=1:1:lenB
if(isnan(B(i)))
out = -1;
return
end
end
  
for i=1:1:lenA
if(isinf(A(i)))
out = -2;
return
end
end
  
for i=1:1:lenB
if(isinf(B(i)))
out = -2;
return
end
end
  
if(ischar(A) || ischar(B))
out = [-3];
return
end
if(islogical(A) && islogical(B))
if(length(A) == length(B))
out = and(A,B);
return
else
out = -4;
return
end
  
elseif(isnumeric(A) && isnumeric(B))
if(length(A) == length(B))
out = abs(A-B);
return
else
out = -5;
return
end
end
out = -6;

end
