β¦ Synopsis
By
using complex representation and GSVD of quaternion matrices, we define the norm of quatemion matrices, study the equality constrained least squares problem of quatemion matrices, give the necessary and sufficient conditions for the quatemion equality constrained least squarea problem to have solutions, and finally derive a practical algorithm.

We present some perturbation results for least squares problems with equality constraints. Relative errors are obtained on perturbed solutions and Lagrange multipliers of the problem, based on the equivalence of the problem to a consistent system of linear equations.
## Abstract In this paper, two new matrixβform iterative methods are presented to solve the leastβsquares problem: and matrix nearness problem: where matrices $A\in R^{p\times n\_1},B\in R^{n\_2\times q},C\in R^{p\times m\_1},D\in R^{m\_2\times q},E\in R^{p\times q},\widetilde{X}\in R^{n\_1\time
