lsqnonneg

Nonnegative linear least-squares solution.

📝Syntax

x = lsqnonneg(C, d)
[x, resnorm, residual, exitflag, output, lambda] = lsqnonneg(C, d, options)

📥Input Arguments

📤Output Arguments

Parameter	Description
x	nonnegative least-squares solution.
resnorm	squared residual norm.
residual	d - C*x.
lambda	KKT multipliers for nonnegativity constraints.

📄Description

lsqnonneg solves min norm(C*x-d)^2 subject to x >= 0 using an active-set method.

💡Examples

C = [1 0; 0 1; 1 1];
d = [1; 2; 3];
[x, resnorm] = lsqnonneg(C, d)
