Research into the Method of Accuracy Optimization in Survey Programming of MATLAB
In the process of survey data processing, solving problem can usually be attributed to linear equations like Ax=b, but under some circumstances, the equations may be ill-conditioned, if conventional method of MATLAB still be used in programming, the solution worked out may not be the true one. To solve this problem, method of introducing symbolic calculation into programming has been proposed in order to make ill-conditioned feature of designed equations better and improve stability and accuracy of parameter, the superiority in GNSS elevation fitting has been proved by triple-order polynomial curve-fitting method.
