WebMar 23, 2024 · Let's say I have the following 14x14 matrix A. If it is a graph, each node has a maximum neighbors = 6. I want to create a matrix which will be 14x6. So, each row will have maximum 6 items and the values will be the non-zero items (keeping original sequence) from the original matrix, followed by zero padding. WebThe "Legacy" method uses the generator called by Random in versions of Mathematica prior to Version 6.0. A Marsaglia – Zaman subtract ‐ with ‐ borrow generator is used for reals. The integer generator is based on a Wolfram rule 30 cellular automaton generator.
