optR.fit {optR}

Fitter function for Linear/Non-linear system with form Ax=b

Description

optR.fit is fit function for determing x for System with form Ax=b

Usage

## S3 method for class 'fit'
optR(x, y = NULL, method = c("gauss, LU, gaussseidel", "cgm"),
  iter = 500, tol = 1e-07, ...)

Arguments

x

: Input matrix

y

: Response is matrix

method

: "gauss" for gaussian elimination and "LU" for LU factorization

iter

: Number of Iterations

tol

: Convergence tolerance

...

: S3 Class

Value

U : Decomposed matrix for Gauss-ELimination Ax=b is converted into Ux=c where U is upper triangular matrix for LU decomposition U contain the values for L & U decomposition LUx=b

c : transformed b & for LU transformation c is y from equation Ux=y

estimates : Return x values for linear system

seq : sequence of A matrix re-ordered

Examples

# Solving equation Ax=b
A<-matrix(c(6,-4,1, -4,6,-4,1,-4,6), nrow=3,ncol=3, byrow = TRUE)
b<-matrix(c(-14,36, 6), nrow=3,ncol=1,byrow=TRUE)
Z<-optR(A, b, method="gauss") 

# Solve Linear model using LU decomposition (Supports Multi-response)
Z<-optR(A, b, method="LU")

# Solving the function using numerical method
Z<-optR(A, b, method="cgm")
