elements = elem( values , rows , cols = -1 , ... )
Utility function for enabling on the fly elements' extraction, even from a temporary variable that is unnamed and whose lifetime ends after the evaluation of the command which created it. A subset of elements of such a temporary variable cannot be explicitly and portably accessed without assigning the temporary variable to another explicit variable or passing it to a function. This utility function works around the issue while also providing advanced methods for indexing (even multiple arrays at the same time).
values ::cellnumstring:: Array of objects. rows ::cellindex:: Scalar, vector or matrix of row indices, or cell-array whose elements are scalar, vectors or matrices of row indices (row subscripts). cols ::index,string:: Scalar, vector or matrix of column indices, or ascii flag indicating the dimension along which the rows indices have to be considered. A cell-array whose elements are all either column indices or dimensions, is also supported. Valid options for the ascii flags are: Option │ Meaning ────────────┼────────────────────────────── 'r' │ Rows (equivalent to -1). ────────────┼────────────────────────────── 'c' │ Columns (equivalent to -2). Output arguments: elements ::generic::

The Mastrave modelling library is committed to provide reusable and general - but also robust and scalable - modules for research modellers dealing with computational science. You can help the Mastrave project by providing feedbacks on unexpected behaviours of this module. Despite all efforts, all of us - either developers or users - (should) know that errors are unavoidable. However, the free software paradigm successfully highlights that scientific knowledge freedom also implies an impressive opportunity for collectively evolve the tools and ideas upon which our daily work is based. Reporting a problem that you found using Mastrave may help the developer team to find a possible bug. Please, be aware that Mastrave is entirely based on voluntary efforts: in order for your help to be as effective as possible, please read carefully the section on reporting problems. Thank you for your collaboration.
