Question

In this exercise, you will create, if possible, an m by n matrix A, such that, an (i, j)-entry of the matrix A is the sum of the indexes i and j, where i runs from 1 to m and j runs from 1 to n. You can use for loop for constructing matrix A.

You will also check in your code whether the given variables m and n are integer elements. The conditional statement “if … else”

and the MATLAB function mod can be used here. If both m and n are integer, proceed to the calculation of the entries of the matrix A. If not, the outputs have to be “A = empty_matrix” followed by the comment “m and n must be integer”.

Please follow the steps outlined below:

**Create the function in MATLAB

A=sums(m,n)

Explanation / Answer

Create a function in the script file for [A]=sums(m,n).

function[A]=sums(m,n)

if (m>0 && n>0 && mod(m,1)==0 && mod(n,1)==0)

disp('m and n are integers')

for i=1:m

for j=1:n

A(i,j)=i+j;

end

end

else

A=[ ]                % [ ] is a empty matrix

disp('m and n must be integers')

end

end

Test 1: First test for non-integers.

A=sums(2.3,4)

m and n must be integers

A =

     [ ]

Test 2: Test for negative row/column size.

A=sums(-2,4)

m and n must be integers

A =

     [ ]

Test 3: Test for with correct values.

A=sums(2,4)

m and n are integers

A =

     2     3     4     5

     3     4     5     6
