how to solve equations?

Hi,

I have calculated the future value of a string of future cash flows. I know what to know what period payments are required to get to a future amount that equals a certain amount. So: For what ‘i’ does the following equation hold: 10.000=fvfix(0.05,10,’i’)

kr,

you can use fsolve to solve equation, but note that it will only find 1 local solution. it seems that in in your case there is an analytical solution as well: it would be better to calculate that directly, if possible

with fsolve you have to formulate as: value=0, so in your case it would look like: f_sol=@(x)fvfix(0.05,10,x)-10000; fsolve(f_sol,x0)
