| Post subject: | rMatrixEvd for matrix with real eigen values |
I'm trying to upgrade from version 3.10.0 (https://www.nuget.org/packages/alglibnet2/) to the latest 3.17.0. In the new version rMatrixEvd gives complex eigen values with small imaginary parts, for matrices with real eigen values. The function worked alright with 3.10.0. Is there any flag to adjust the precision in the new version? Here is an example matrix: 1.96, 2.2863, -6.194026. 1.54119028, 1.55673133 1, 0, 0, 0, 0 0, 1, 0, 0, 0 0, 0, 1, 0, 0 0, 0, 0, 1, 0 |
