TGF graph data format. Used for the storage and exchange of graphs. TGF is an acronym for Trivial Graph Format. Stores directed graphs. Stores at most one label per vertex ...

Consider the matrix differential equation where the initial value y_0 y(0)∈^m×p is given. Assume that y_0^Ty_0I, that the solution has the property of preserving ...

GraphPlot[{v i 1 -> v j 1, v i 2 -> v j 2, ...}] generates a plot of the graph in which vertex v_ik is connected to vertex v_jk.GraphPlot[{{v i 1 -> v j 1, lbl_1}, ...}] ...

AllPairsShortestPath[g] gives a matrix, where the (i, j)\[Null]^th entry is the length of a shortest path in g between vertices i and j. AllPairsShortestPath[g, Parent] ...

MultiedgeStyle is an option for GraphPlot and related functions that specifies how to draw multiple edges.

RidgeFilter[image] computes a measure for the presence of a ridge for each pixel in image.RidgeFilter[image, \[Sigma]] uses the specified ridge scale \[Sigma].

SelfLoopStyle is an option for GraphPlot and related functions that specifies how to draw self-loops that connect a vertex to itself.

VertexRenderingFunction is an option for GraphPlot and related functions that gives a function to generate the graphics primitives to use in rendering each vertex.

Making lists from functions. This makes a list of 5 elements, each of the form p[i]. Here is another way to produce the same list.

Cofactor[m, {i, j}] calculates the (i, j)\[Null]^th cofactor of matrix m.
