 Dope vector - Wikipedia, the free encyclopedia
In computer programming, a dope vector is a data structure used to hold information about an array, especially its memory layout.
A dope vector contains information about the rank of an array, the extents of an array, and the stride of an array.
It is often used in compilers to pass entire arrays between procedures in a high level language like Fortran.

In linear algebra and related areas of mathematics, the null vector or zero vector in a vector space is the uniquely-determined vector, usually written 0, that is the identity element for vector addition.
Vector (spatial): In physics and engineering, ''vector'' most often refers specifically to an object that has a special relationship to the spatial coordinates/directions, that is, an element of a tangent bundle.

 dope-vector based IPC interface
One of the major differences between the two implementations is that the Lava/L4 trap interface uses a dope vector.
If no string is to be transmitted, then the dope vector register pointer is empty and the trap interface can skip the work necessary to do a bounds check on the string buffer and move the data.
Given this, it is possible to specify the receive-string in a dope vector.

Dope Vector Representation Comments Dope Vectors are useful when there is not sufficient contiguous space to store an entire multidimensional array.
For example, in a 2-D dope vector array, the 2-D array is stored as a 1-D array of 1-D arrays.
Thus, the higher level 1-D array (the "dope vector") is referenced first, and the entry in that array points to some arbitrary location in memory which holds the contiguous 1-D array for that entry.

 Vectors and Arrays - Language design and implementation
Element access is similar to that for vectors, except that after each index (except the last) is processed, the calculated address is just used as the origin for the next index calculation; if we have processed all the indices then this is the correct address.
Many languages leave this to the implementor; the simplest method is to use the size of a vector element, calculated from its type (which may itself be a vector).

Dope vector is usually separate from pointer to data.
The third class can still be put in a procedure's activation record; you put the dope vector and a pointer at a fixed offset from the FP and the data itself higher up in the frame.
Now all dynamically-sized objects consist of three things: a dope vector, a pointer at a known place, and real data in the variable-size part of the frame.

 Charles.Vectors.Limited_Bounded
A vector is a generalization of an array-based stack.
This vector type is bounded, which means the size of the internal array is fixed at the time of declaration.
The length of a vector indicates how many elements of the internal array are "active," and the size indicates the length of the internal array.

 Diamond Lab - Gene Therapy
We formulated adenovirus (AdV) vectors with cationic steroid liposomes containing dexamethasone–spermine (DS)/dioleoylphosphatidylethanolamine (DOPE) in an effort to overcome the lack of apically expressed AdV vector receptors on airway epithelial cells and to reduce the inflammation associated with AdV vector exposure.
An AdV vector (1 to 2.5 x10^11 genome copies) expressing human placental alkaline phosphatase or B-galactosidase (LacZ) was delivered alone or complexed with DS/DOPE, DC-Chol/DOPE, or dexamethasone to C57Bl/6 mice via intranasal instillation.
Viral vectors can be formulated with DS/DOPE to improve targeting to the airway epithelium in vivo and to attenuate vector-induced inflammation through the pharmacological activity of DS.

In computer programming, a group of homogeneous elements of a specific data type is known as an array, one of the simplest data structures.
An array is similar to, but different from, a vector or list (for one-dimensional arrays) or a matrix (for two-dimensional arrays).
While this is true, a one-based or n-based array access can be easily optimized — with common subexpression elimination or the use of a well-defined dope vector, to name only two options available.

 Run Time Design
It is, however, possible to put the dope vectors at fixed offsets from some base, which might, in extreme cases, need to be computed at runtime.
If we assume that dope vectors may be used to describe the actual types, and that these dope vectors may have fixed size, then these may be placed where we have indicated instance variables.
The data in the dope vectors may then be used to allocate storage for the indicated fields, either at the end of the object-segments indicated above, or elsewhere in the heap or stack.

 CAGED PHOSPHOLIPIDS - Avanti Polar Lipids
Liposomal gene therapy vectors that penetrate cells by endocytosis must escape an endosomal compartment in order to enter the target cell's nucleus.
N-Citraconyl- dioleoylphosphatidylethanolamine (Cit-DOPE), a derivative of dioleylphosphatidylethanolamine (DOPE) that hydrolyzes rapidly at pH 5 to yield DOPE, was synthesized and incorporated with DOPE and folatepolyethyleneglycol-DOPE into liposomes.
Folate-labeled gene transfer vectors were prepared by compacting plasmid DNA with polylysine at a 1:0.75 (w/w) ratio and complexing the condensed cationic plasmid with the above anionic liposomes.

Eg replace float by double, vector by dvector and matrix by dmatrix, etc. You will also need to edit the function definitions to use the version acceptable to your compiler.
Then any vector in Numerical Recipes with subscripts starting from 1 in a function call can be accessed by a RowVector, ColumnVector or DiagonalMatrix in the present package.
So matrices or vectors must be correctly dimensioned before a Numerical Recipes routine is called.

It is only by passing a dope vector that the compiler can arrange to have the calling procedure pass information about the data layout of the actual argument to the called procedure.
The rationale for introducing assumed-shape dummies in Fortran 90 was to provide a mechanism for passing information the base address of the actual argument.

 Arrays in Blitz++
The library handles parsing and analysis of array expressions on its own using the expression templates technique, and performs optimizations (such as loop transformations) which have until now been the responsibility of compilers.
The goal of the Blitz++ library is to provide a solid ``base environment'' of arrays, matrices and vectors for scientific computing in C++.
This eliminates the need to represent each vector field as three separate arrays, common in Fortran implementations.
