x finds y using newtons method
显示 更早的评论
I'm a little confused on how I would go about this problem. The function y=f(x) which given x finds y such that x=y+1/8cos(y^2) by performing 5 iterations using newtons method. The code should be within function definition.
Given:
function y=f(x)
y=x
[code goes here]
endfunction
any help with this would help me out tremendously!

This is your homework. We can expect, that you have learned the details of the Newton method in the lessons, or you can find them at least in your text book or at https://en.wikipedia.org/wiki/Newton%27s_method. The WikiPedia article contains a "pseudo code" example, which can be converted to Matlab very easily.
Please try it and ask a specific question in case of problems.
