matplotlib 3.5.1

ParametersReturns
get_function_derivatives(self, alpha, J, ecc, dofs)

Parameters

*alpha* is a (N x 3 x 1) array (array of column-matrices of :
barycentric coordinates) :
*J* is a (N x 2 x 2) array of jacobian matrices (jacobian matrix at :
triangle first apex) :
*ecc* is a (N x 3 x 1) array (array of column-matrices of triangle :
eccentricities) :
*dofs* is a (N x 1 x 9) arrays (arrays of row-matrices) of computed :
degrees of freedom. :

Returns

Returns the values of interpolated function derivatives [dz/dx, dz/dy]
in global coordinates at locations alpha, as a column-matrices of
shape (N x 2 x 1).

Examples

See :

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
