Hello,

I am not a math major but an ocean scientist. I am trying to solve an equation for wave motion under water and I need help.

I would like to use Matlab to solve for a variable using an iterative approach but I have to understand what that really means before I do that. The equation is:

Where z, v, and U are known integers, * = multiply, / = divide

I would like to find u_star,

U = (5.5/u_star) + (2.5*(ln((u_star*z)/v)))/u_star

Do you have any suggestions about which iterative method would work best?

Do you have any suggestions about where to go to find a SIMPLE explanation about the application of an iterative method online?

Should I not do this because it is really complicated?

Thank you for reading my post and thank you for any help/suggestions you have to offer, they are greatly appreciated.
