Retrospectively amassed length information are frequently stated incorrectly. an incredible kind of such an mistakes is heaping - respondents are inclined to round-off or round-up the knowledge in accordance with a few rule of thumb. for 2 detailed circumstances of the Weibull version we examine the behaviour of the 'naive estimators', which easily forget about the size errors as a result of heaping, and derive closed expressions for the asymptotic bias. those effects provide a proper justification of empirical facts and simulation-based findings stated within the literature. also, occasions the place a extraordinary bias should be anticipated should be pointed out, and a precise bias correction could be played.

3. Accessing VTK Object’s Data It might happen that we want to extend visualization programs by functions written in Fortran or we have large Fortran legacy code we would like to interface with visualization program written using VTK library. One problem that immediately appears is that in Fortran (including Fortran 90) we do not have direct access to C++ objects. In theory it is possible to pass C++ object pointer to a Fortran function and then knowing the memory layout of the object manipulate it directly from Fortran but this is restricted to simplest cases and is highly not portable.

In lines 15 to 23 we get the value of the objects which were passed as command arguments. In line 25 we call our C ”fast addition” function and in line 26 we create the result object then set it as the result of the command. The example only touches the issue of creating command procedures in C. ). Creating a command procedure is only half of the job. Tcl must be informed about the new command, so that whenever it encounters the command name in a procedure call context it knows what to do. We are going to provide new built-in Tcl Add command as a dynamically loadable package.
