Critical issue in PTC Mathcad 15.0 M040

[bedmonds]

We’ve recently found, through customer reports and our own testing, an issue with matrix definition and evaluation that was introduced in PTC Mathcad 15.0 M040. This issue affects matrices of 256 elements or larger and can lead to a failure to evaluate and the possible loss (if document is saved after failure to evaluate) of matrix definition regions themselves. This tech support bulletin has more information on this issue.

We intend to release PTC Mathcad 15.0 M045 as quickly as possible which will include a fix for this issue. The release date for PTC Mathcad 15.0 M045 will be posted on the Product Calendar page soon.
