Hello, i am a newbie at Matlab, i am searching for a function to cover my needs.

It is about bond yield, its maturity, face value and price.

A function that, y =yield(price, cr, maturity, cf, fv) that takes bond price, coupon rate, coupon frequency, maturity and face value, and returns the yield to maturity of the corresponding bond.

I could do something like
c./((1+y).^t)
(-t(m,:)./(1+y(m,:)))./((1+y(m,:)).^t(m,:))

but i couldn't solve the whole problem.

Is there any script that can be useful for y =yield(price, cr, maturity, cf, fv)? Thanks in advance.
