2D covariance, elipse Geodesy - Amer7 - 12-29-2021 12:35 PM 2D Covariance matrix, elipse calculator with all elements. Input values of Cx matrix (2x2, or 4x4 ) into default matrix memory M1 For 4x4 Enter Variance matrix into M2 To calculate the standard axis for elipse use the Elipsa gresaka 21 (4x4), or for (2x2) use Elipsa21-2x2 To calculate the axis values for chi or Fisher distribution use Chi_Fi, enter the values of CX in M1, and the values of Chi and Fisher in start of the program. |
