use fminsearch and fzero together

hello, How to use fminsearch and fzero together, i mean i wanna minimize obj.func but there are some variables that need fsolve first. can it combine? thanks

Yes. The handle you provide to fminsearch can be to a complete function definition that takes whatever computation it needs to determine the value associated with the inputs.

thank you, but i'm still confused for example

 mfile-1 (name of mfile=min)
 [value n,fvlag]=fminsearch(@(n) trialp(n),[1 2])
 mfile-2 (name of mfile=optp)
 function res=optp(n)
 m=n(1);
 r=n(2);

bubblep %nameofmfile%
res=7.2-p
end

mfile-3 (name of m-file =bubblep)
[p,fvlag]=fzero(@(p) cal(p),8)

mfile 4 (name of mfile=cal)
function val=cal(p)
m=p+n+2
val=m-1
end

mfile 4 need parameter that the result or trial from fminsearch, so how can i make the function ? need your help. thanks

@ni made veriska: DO NOT name any function or Mfile min: this will cause shadowing of the inbuilt min function, and prevent that very important function from working.

Your code shows calling trialp and shows the definition of optp but there is no definition for trialp and no call to optp or the "min" that you show as your first file
