This article introduces the new version of our system for the recognition of on-line handwritten mathematical expressions. The previous version was capable to recognize the most common mathematical expressions, such as expressions of calculus, following the usual mathematical conventions. This version improves and extends our technique, allowing the recognition of structures described by tabular and multiline arrangements, such as matrices and systems of equations. The recognition results are
