BarBor {BarBorGradient} | R Documentation |
Approximate a functions minimum with double monoton method.
BarBor(exp,eps,x,v,n)
exp |
Expression of the function to be minimized. |
eps |
Precision of the approximation, recommended value is 10^-10. |
x |
Starting point of the approximation. |
v |
A character vector of the functions variables, for instance the two dimension fuction x1*x1+10*x2*x2 needs a c("x1","x2") vector. |
n |
Maximum setps to make while approximating, if the calculation reaches this number it exits with the current value and point. Recommended to be 10000. |
test1 = expression(x1*x1+10*x2*x2) eps = 10^-15 x = c(3,4) v = c("x1","x2") n = 10000 BarBor(test1,eps,x,v,n)
