Putting Output values into a matrix.

Hi, I have an if statement within a double for loop. I would like to be able to put the two index values that satisfy the if statement into a matrix that I can then manipulate etc. Currently, I am just using "disp" to display the two index values. How can I go about putting the values into a matrix?

One approach:

vals = [];
for k1 = 1:10
    for k2 = 1:10
        if k1 == k2                             % Test Condition
            vals = [vals; k1 k2];               % Store Index Values
        end
    end
end

Here, the ‘vals’ matrix will be:

vals =
     1     1
     2     2
     3     3
     4     4
     5     5
     6     6
     7     7
     8     8
     9     9
    10    10

What if I want to put a title for each column?

Use array2table and then add the variable (column header) names.
