Hello!
Can anyone explain me what solve() function does: Gaussian elimination or
iterative, numeric solve? In addition, I would need both the Gaussian
elimination and iterative solution for the course. Are the two built in

Thank you so much! This is very useful!
Any thoughts about how to run Gaussian elimination?
Do some searching?
RSiteSearch(gaussian elimination, restrict = c(Rhelp10, Rhelp08,
Rhelp02, functions ) )
returns (among other things) a link
If A is a squared matrix, solve(A) gives the inverse of A; if you have a
system of linear equation AX=B, solve(A,B) gives the solution to this system
of equations. For example:
x-2y =1
-2x+3y=-3
A=matrix(c(1,-2,-2,3), ncol=2, byrow=T)
B=c(1,-3)
# to get the inverse of A
solve(A)
Hello!
Can anyone explain me what solve() function does: Gaussian elimination
or iterative, numeric solve? In addition, I would need both the Gaussian
elimination and iterative solution for the course. Are the two built in R?
Thanks!
