Hi
How Can I write this this matlab code in R:
options=optimset('TolFun',1e-9,'TolX',1e-9,'MaxIter',1e8,'MaxFunEvals',1e8);
c=c/2;
[alpha, delta, epsilon, nofcup] = ustrs(set_date,mat_date);
y = fminsearch('pbond',.15,options,p,c,nofcup,delta/epsilon);
y = 200*y;
Note
pbond is a function in Matlab I already wrote in R
ustrs is...

r's optim vs. matlab's fminsearch
...tlab have default settings for reflection, contraction, and expansion, and
if so what are they? Are there other reasons optim and fminsearch might
work differently?
Thanks.
***Matlab's fminsearch defaults***
MaxFunEvals: '200*numberofvariables'
MaxIter: '200*numberofvariables'
TolFun: 1.0000e-004 #Termination tolerance on the function
value.
TolX: 1.0000e-004 #Termination tolerance on x.
***R's optim defaults (for Nelder-Mead)***
maxit=500
reltol=1e-8
alpha=1.0 #Reflection
beta=.5 #Contraction
gamma=2.0 #Expansion
