| Aufgabe 1 | | To find the zero(s) of a function |
| Aufgabe 2 | | Problem with fzero function in Matlab |
Hello,
I have the following problem with Matlab and I would be very happy if anyone could help me:
I use fzero to find the zero of a function gamma(N).
This works without any problems.
I now want to introduce another variable alpha so that the function gamma depends on two variables N and alpha. In other words, for a given value of alpha, I want to find N* so that gamma(N*)=0.
Nur für Erst-Poster
Of course, fzero doesn't work with a function composed of two variables.
Does anyone have an idea about how to solve this problem?
Ich habe diese Frage in keinem Forum auf anderen Internetseiten gestellt.

Hello Yaya,
i've had a look on matlab help and foundd:
X = FZERO(FUN,X0,OPTIONS,P1,P2,...) allows for additional arguments
which are passed to the function, F=feval(FUN,X,P1,P2,...). Pass an empty
matrix for OPTIONS to use the default values.
--> the parameters P1,...,PN are passed throuch FZERO to the function FUN specified in your call.
For your problem it should be:
x = fzero('gamma',N,[],alpha);
