The matrix least squares(LS) problem minX ‖AXBT-T‖ F is trivial and its solution can be simply formulated in terms of the generalized inverse of A and B.Its g
On the basis of the Cauchy integral formulas for regular and biregular functions, we define some Cauchy-type singular integral operators. Then we discuss the H
