I am not sure if this is the correct place to ask this question!

Is there a data set such as the University of Florida Sparse Matrix Collection which is produced from stencil operations?

Or is there a way to generate such sparse matrices, maybe using Matlab?

I assume that you are looking for matrices that come from, e.g., finite differences applied to a PDE.

You may try the matrix market. There you can search for matrices from common PDE applications.

In Matlab there is the function del2 that returns a matrix representing a discrete Laplace operator.

  • $\begingroup$ In the field of numerical analysis, I know the stencil as an illustration of the geometric arrangement of the nodes that are used to approximate a differential operator e.g. via finite differences. See the Wikipedia article although it is not very extensive. $\endgroup$ – Jan Nov 23 '13 at 16:43
