Describe the issue: Hi, I found that in-place modificaiton [:] for 1d numpy array a is not working (with values automatically set to be 0) in the following code, while it works fine for the 2d numpy array A. This is quite strange to me, ...
This is not a stack array, it's a large, statically declared array, likely in COMMON. The individual array won't be over 2GB , because the compiler would tell you if it was, but if multiple arrays are large, you can also hit the limit. The Wi...
The EDM4hep default data model definition includes multiple fields defined as fixed-length single-dimensional std::array of float, e.g. std::array<float,6> covMatrix in edm4hep::TrackerHit 1. When data is written with these fields, it is not readable with ROOT, and an error is returned...
You may consider whether to change the order in which the matrix is stored on mass storage (disk drive, SSD, USB drive, etc.) to make the Fortran program more efficient, if the matrix is not stored in the order that I described in the preceding paragraph. For instan...
Note that is not necessary to use@:inside a code block if you won’t be starting with plain text. As you have seen before, HTML markup elements can be included at any part of the code. Add the optative section “Header”, which was defined in the layout page. This will render a “...
The values of featUiLabelNameId, featUiTooltipTextNameId and firstParamUiLabelNameId are expected to be in the font-specific name ID range (256–32767), though that is not a requirement in this Feature Parameters specification. The value of firstParamUiLabelNameId + numNamedParameters - 1 ...
