Error using / matrix dimensions must agree

I have to plot the function y=Mt*(1/ec)*(1/sqrt(1-((ec-h)./ec).^2)) but it gives me this error, where did I go wrong

The ‘y’ expression is not a function of ‘x’.

Correcting that (and assuming the independent variable is actually ‘ec’) —

ec = linspace(0, 0.035, 50);
Mt = rand;                                          % Missing Value
h = rand;                                           % Missing Value
y=Mt*(1./ec).*(1./sqrt(1-((ec-h)./ec).^2));

figure
plot(ec, real(y), 'DisplayName','Real')
hold on
plot(ec, imag(y), 'DisplayName','Imaginary')
hold off
ylim([-1 1])
legend('Location','best')

There were also some missing element-wise operators.

It works, I had to pay attention to "./", thank you

As always, my pleasure!
