E(z)=(lamb​da*z*R)/(2​*E_initial​*((z.^2+R^​2)^(3/2)))

Why is this wrong ? It won't give me an answer

Answer 1

[Walter Roberson]

E = (lambda .* z .* R) ./ (2 .* E_initial .* ((z.^2 + R.^2).^(3/2)))

[Maria V Alberico]

Thank you but it's still not working.

[Walter Roberson]

What are the values for your variables? What result are you getting? What result do you expect to see?

Perhaps you need

E = @(z) (lambda .* z .* R) ./ (2 .* E_initial .* ((z.^2 + R.^2).^(3/2)))

if you are trying to create a function
