MATLAB: Is this right

factorialfor loop

Okay so my task is:

I have to make a script in matlab, which gives back the product of the first 10 element.(of this equation)

fn=((n^2)+n)/((n^3)+n!-4)

Is this right?

y=1
for i=1:10
    y=y*(((i*i)+i)/((i*i*i)+(factorial(i))-4))
end

Thanks for helping, it means a lot.

MATLAB: For loop nested in while loop problem

I realized that I didn't reinitialize my "a" variable, thanks to Barmar's comment. Although the code might not look very efficient, this is what works for me:

    a = 10;
    k = 0.5;
    n = 2;
    while a < 300
        a = 10;
        for m = 1:5
            a = a + (a*k) + n;
        end
        if a >= 300
            break
        end
        n = n + 1;
    end

MATLAB: Is it right

Looks right to me. I just fancied it up a bit:

x = [-3:3]
y = 3*x.^4-6*x.^3+8*x.^2+4*x+90;
z = 3*x.^3+5*x.^2-8*x+70;
plot(x, y, 'bo-', 'LineWidth', 2)
hold on;
plot(x, z, 'rd-', 'LineWidth', 2)
grid on;
xlabel('Voltage (V)', 'FontSize', 20)
ylabel('Current in Milliamperes (mA)', 'FontSize', 20)
title('Voltage vs. Current', 'FontSize', 20)
legend('y', 'z', 'Location', 'north');

set(gcf, 'Units', 'Normalized', 'OuterPosition', [0, 0.04, 1, 0.96]);
