basic_fmatrix
Definition at line 7939 of file cfun.h.
Jacobi matrix.
Creates basic_fmatrix object as Jacobi matrix of calling vector of functions. First variable to compute partial derivatives is set by nfrom index (0-based, 0 by default), the number of variables to use is set by vars argument (0 for all, default). Number of rows of the Jacobi matrix built is equal to vector's size, number of columns is the number of variables used to compute it. Function throws cvmexception if the numbers are out of boundaries.
- Example:
using namespace cvm;
try{
funcs.push_back("{x,y} x+y+1");
funcs.push_back("{x,y} x*y");
funcs.push_back("{x,y} x^y");

Jacobi matrix.
Computes Jacobi matrix of calling vector of functions and sets fmj basic_fmatrix object to it. First variable to compute partial derivatives is set by nfrom index (0-based, 0 by default), the number of variables to use is set by vars argument (0 for all, default). Number of rows of the Jacobi matrix built must be equal to vector's size, number of columns is the number of variables used to compute it. Function throws cvmexception otherwise.
- Example:
using namespace cvm;
try{
funcs.push_back("{x,y} x+y+1");
funcs.push_back("{x,y} x*y");
funcs.push_back("{x,y} x^y");
