A cramer rule for solution of the general restricted linear equation∗
Yonglin Chen · Linear and Multilinear Algebra · 1993
For the unique solution or one of solutions of a general restricted linear equations where A∊ C m×n b∊ AT, and Tis an arbitrary but fixed subspace of Cn , we derive a Cramer rule (determinantal formula) and give a unified treatment of related problems considered in references [2, 3, 4, 5, 6].
