## LSEQUAL Linear Least Squares with Equality ...

lsequal Linear Least Squares with Equality Constraints by Duane Hanselman.

LSEQUAL(A, b, B, d) returns the linear_least_squares solution x to the linear system of equations A*x = b, with added linear equality_constraints described by B*x = d. That is, LSEQUAL minimizes the sum of squared errors (b - A*X)'*(b - A*X), subject to B*x = d.

A is M-by-N, b is M-by-1

B is P-by-N, d is P-by-1

B must have full rank, i. e. , the constraints must be independent.
