func SCA ¶
SCA solves the non-negative least squares problem.
Argument A represents a design or input matrix. Each element of A must have the same length. b represents a measurement or output vector. δ is a tolerance for the result.
Iteration will stop when the least squares objective is within δ of an optimal solution.
The result x returns coefficients of the fitted linear function, it will have the same length as elements of A. Result i is the number of iterations performed. An error is returned if A and b are not the same length.
func SCAKKT ¶
SCAKKT solves the non-negative least squares problem.
Argument A represents a design or input matrix. Each element of A must have the same length. b represents a measurement or output vector. ε is a tolerance for stopping iteration.
Stopping criteria for this function are based on Karush–Kuhn–Tucker conditions (see https://en.wikipedia.org/wiki/Karush%E2%80%93Kuhn%E2%80%93Tucker_conditions). Iteration stops when a result is non-negative and the gradient of the objective function is within ε of KKT conditions. The advantage of this function over SCA is that stopping conditions are simpler to compute and so each iteration takes less time. The disadvantage is that the ε of this function is less obviously related to the objective function and stopping criteria are less clear.
The result x returns coefficients of the fitted linear function, it will have the same length as elements of A. Result i is the number of iterations performed. An error is returned if A and b are not the same length.
func SCALimit ¶
SCALimit solves the non-negative least squares problem.
Argument A represents a design or input matrix. Each element of A must have the same length. b represents a measurement or output vector. limit is a maximum number of iterations.
Iteration will stops after limit iterations or when the result does not change from one iteration to the next. If argument limit is < 0, the package value Limit is used.
The result x returns coefficients of the fitted linear function, it will have the same length as elements of A. Result i is the number of iterations performed. An error is returned if A and b are not the same length.
