 `BProbeM, a fuzzy quantum geometry scanner`, is a [Wolfram Mathematica](https://www.wolfram.com/mathematica/) package. It is the implementation of an algorithm which rasterizes the semi-classical limit of a fuzzy brane described by a set of matrices. 
 
-BProbeM is a [fork](https://en.wikipedia.org/wiki/Fork_(software_development)) of BProbe by Lukas Schneiderbauer, adding several features for scanning such as the newly added directional scans, improves and completes missing documentation and improves computational time by changing how some internal procedures are handled.
