I am getting multiple curves instead of getting one curve by using the following code. here ep_1 and ep_2 data I am importing from outside which contains 69 data points.
y = lambda./(sqrt((ep_d.*ep)./(ep_d+ep))- sin(theta*(pi/180)));
I have attached my output but here I am supposed to get only one curve. Kindly help me in this problem. How can I get one curve only?
