VCG - Linear Field 2D

Description

2D Linear Field flow defined by its velocity in each point given as the product of matrix A and position vector.

Details

The Linear Field 2D flow is defined by the equation $v = A*\vec{x}$ with the rows of matrix A being definde by the Parameters A1 and A2 . Alternatively, the columns of the matrix A can be interpreted as eigenvectors through the parameter Eigenvectors . It's then possible to define the corresponding real eigenvalues and set the number of complex eigenvalues.
