Indirect Adjustment and the Matrix QR Decomposition
Liting Zhang · Journal of East China Institute of Technology · 2009
Indirct adjustment is the basic method in survey data procession.As the observation conditions is limited,the ill-conditioning problem may be resulted in.In order to overcome the shortcomings,the matrix QR decomposition method and its applications in direct solving the indirect adjustment are studied.The formulas for solving the equal-precision Observation,weighted observation and with restricted conditions are also presented,which expanded the minimum least squares solution of linear system of equation based on matrix QR.
