How to show each iteration in for loop?

initialX = input('\nWhat would you like your starting x value to be?\n');
initialY = input('\nWhat would you like your starting y value to be?\n');

xo = initialX;
yo = initialY;
dydx = 0;

for j = xo:deltaxem:sizeOfGraphXPositive
    
    xo = j;
    yo = yo + (dydx .* deltaxem);
    dydx = xo + yo;
    
    plot(xo, yo, '*', 'linewidth', 4); hold on
    xlim([-sizeOfGraphXPositive sizeOfGraphXPositive]);
    ylim([-sizeOfGraphYPositive sizeOfGraphYPositive]);
    axis equal
    title("Euler's Method");
    xlabel('X Values');
    ylabel('Y Values');
    
end

What specifically do you mean by "show each iteration"? What do you want to have happen that your current code doesn't do?

I want to display the iterations of xo, yo, and dydx in a table. Specifc xo and yo values correspond to the value of dydx. However, I am not sure how to display a value that was iterated inside the for loop, outside of the for loop.

Add this after dydx=... line:

fprintf('xo = %10.5f    yo = %10.5f    dydx = %10.5f \n', xo, yo, dydx);
