Hi all, I would like to ask that is there any function in R which can solve nonlinear system equations with several variables. Thats mean some functions similar to the 'fsolve' or 'fzero' in matlab.

Hey, I was wondering if there existed a R function similar to 'fsolve' or 'fzero' Matlab functions? Thanks! Francois Aucoin [[alternative HTML version deleted]]

Hi all, This is probably a blindingly obvious question: Why does it matter in the uniroot function whether the f() values at the end points that you supply are of the same sign? For example: f <- function(x,y) {y-x^2+1} #this gives a warning uniroot(f,interval=c(-5,5),y=0) Error in uniroot(f, interval=c(-5, 5), y = 0) : f() values at end points not of opposite sign #this doesn't give a

All functions referenced via __PV_IS_CALLEE_SAVE() need to be assembler functions, as those functions calls are hidden from gcc. In case the kernel is compiled with "-fzero-call-used-regs" the compiler will clobber caller-saved registers at the end of C functions, which will result in unexpectedly zeroed registers at the call site of the related paravirt functions. Replace the C functions with DEFINE_PARAVIRT_ASM() constructs using the same instructions as the r...

...is: tuki <- function(u, x, a, lambda){ if((lambda%%1>0) & u<0) {u<-(u+0i)} f <- Re(x-(a*(u)^lambda-(1-(u))^lambda)/lambda) f } What I want to do is to find the root, but without specifying the interval within which to search for it. I can do it easily in MATLAB with fsolve() or fzero() functions. I compared results of running root-finding in MATLAB and R: 1) I found (by hand) a suitable interval of u-values for a=5, lambda=0.5 and ran uniroot for x from 1 to 5: ex.: uniroot(tuki, c(-1,1), x=1, a=5, lambda=0.5) The results are the same as I get in MATLAB. 2) nlm() does not...

...d the same results: Digi DEY 8.2.0 works; Arm GNU Toolchain 10/11/12 did not. My last inclination was to do a side-by-side comparison of the configuration and compilation output between Digi DEY 8.2.0 and Arm GNU Toolchain 12. The key differences were checking: if ${CC} supports compile flag -fzero-call-used-regs=all if ${CC} supports compile flag -ftrivial-auto-var-init=zero for sys/sysctl.h for library containing login for closefrom for close_range for library containing dlopen for arc4random for arc4random_buf for arc4random_uniform if libc defines s...
