Field Documentation

◆ _data

double* NNLSQDATA::_data

Internal pointer to all allocated memory for matrix a and arrays b, x, w, and zz, which just point to locations in this array.

Definition at line 134 of file tpclinopt.h.

Referenced by nnlsqDataAllocate(), nnlsqDataFree(), and nnlsqDataInit().

◆ a

double** NNLSQDATA::a

On entry, a[0..n-1][0..m-1] contains the M by N matrix A. On exit, a[][] contains the product matrix Q*A, where Q is an m by n orthogonal matrix generated implicitly by this function.

◆ b

double* NNLSQDATA::b

On entry, b[0..m-1] must contain the m-vector B. On exit, b[] contains Q*B.

◆ depf

double NNLSQDATA::depf

Factor for checking new diagonal element to avoid near linear dependence.

Definition at line 141 of file tpclinopt.h.

Referenced by nnlsq(), and nnlsqDataInit().

◆ index

int* NNLSQDATA::index

An array of working space, index[0..n-1].

Referenced by nnlsq(), nnlsqDataAllocate(), nnlsqDataFree(), and nnlsqDataInit().

◆ iternr

int NNLSQDATA::iternr

Maximum iteration number; set to zero (default) to let the function decide. On exit, contains the number of iterations.

Definition at line 139 of file tpclinopt.h.

Referenced by nnlsq(), and nnlsqDataInit().

◆ m

int NNLSQDATA::m

NLLSQ sample number.

Definition at line 114 of file tpclinopt.h.

Referenced by nnlsq(), nnlsqDataAllocate(), nnlsqDataFree(), nnlsqDataInit(), nnlsqWght(), and nnlsqWghtSquared().

◆ n

int NNLSQDATA::n

NNLSQ parameter number.

Definition at line 112 of file tpclinopt.h.

Referenced by nnlsq(), nnlsqDataAllocate(), nnlsqDataFree(), nnlsqDataInit(), nnlsqWght(), and nnlsqWghtSquared().

◆ rnorm

double NNLSQDATA::rnorm

NNLSQ stores here the squared Euclidean norm of the residual vector, R^2 (Sum-of-Squares).

Definition at line 136 of file tpclinopt.h.

Referenced by nnlsq(), and nnlsqDataInit().

◆ w

double* NNLSQDATA::w

An array of working space, w[0..n-1] for NNLSQ. On exit, w[] will contain the dual solution vector. w[i]=0.0 for all i in set p and w[i]<=0.0 for all i in set z.
