Provide a Matlab code to print Diagonal elements in a matrix

In a given n*n matrix we have to traverse each row and print diagonal elements of each row.

For example m = [4 5 6;7 8 9;10 11 12] , expected answer is :

4

5 7

6 8 10

It would of great help if Code is provided.

Below is the code to print diagonal elements of each row:

m = [4 5 6;7 8 9;10 11 12];

n = size(m,1);

for i=1:n

k=1;

for j=1:i

fprintf('%d ',m(k,i-j+1))

k=k+1;

end

disp(' ');

end

% output:

% 4

% 5 7

% 6 8 10

Logic : first loop ie i=1:n is to traverse row wise in a matrix m and second loop is to print the diagonal elements in a matrix also if we are in first row we have to print one element ,in second row 2 elements is to be printed and in ith row i elements have to be printed, disp function is used to move to new line after printing diagonal elements of previous row.

Thank you , the code itself is self explainatory
