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 a function in Matlab I already convert into r Thank you HI...

...t default options I could find. Are there other options I should to consider? Does Matlab 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 #Co...
