finding the breakeven point

Hi,

I have the following equation:

nanmean(R(x0+1))-(fm1.*BHR)+(ntrades/2*n)*log((1-c)./log(1+c));

I know every parameter except c, which is a breakeven point that I want to compute. i.e. I want the value of c that gives: nanmean(R(x0+1))-(fm1.*BHR)+(ntrades/2*n)*log((1-c)./log(1+c))=0;

does any one know how to do this using matlab?

Are you sure your equation is right? Anyway here is an example with a modified equation:

f = @(c) log((c-1)./log(1+c))
fzero(f,2)
ans =
