finds null space and range of a sparse matrix using lu decomposition.
This routine is devoted to find null space of possibly large matrix fast. Results may be inaccurate if zero and nonzero singular values are not well separated.
This plugin makes your RSS feed for linked-list posts (indicated using a custom field) behave like Daring Fireball.
To use, set the custom field "linked_list_url" to the desired location on a link post. In your RSS feed, the...
Linked list implementation based on Python 2.7 collections.MutableSequence with a few benchmarks comparing the linked list with the built-in list type.
Data structure: Builing Linked-List Class is an article in which author describes the method of generating Linked-List with the help of functionalities of framework Class library. The author gives details about the process of utilizing...
Return the optimal path given the adjacency/cost sparse matrix and source/destination nodes.
Run mexme_dijkstra.m to compile mex-files on your own-plateform
Run test_dijkstra.m for the demo
this is an implementation of queue and stack using doubly linked list. Doubly linked list class may be used seperatly.
An implementation of dictionaries preserving key insertion order. Despite using a doubly-linked list to keep track of the appropriate order, this list is actually embedded in the dictionary. As a consequence, there is little space penalty, and...
Fast version of r576930 reimplemented using a list of lists instead of a node class.
I often return result sets from a database call using a list of dictionary objects. When transmitting the pickled list object over the wire, the size of the pickle greatly effects the speed of the transmission.
I wrote this small class...
This is a program that generates a test problem for linear optimization with a sparse matrix. The test problem is of the kind
min c'*x s.t. Aeq*x=beq lb<=x<=ub
where lb is a zero vector and ub is greater then...
SYNTAX: B = fulltosparse(A)
A = full 2-dimensional double matrix B = sparse 2-dimensional double matrix version of A
This example demonstrates how to populate a sparse matrix. For the purpose of this example, you must...
WordPress Category Posts is a plugin for WordPress that creates a linked list of the posts in a specific category.
Installation :
1. py the wp-category-posts file to /wp-content/plugins/ 2. Activate the plugin at your...
GLL (Generic Linked Lists) is a C library that provides generic linked list support
The image compression routine uses the concept of factorizing the image-matrix & using only the required 'key' values that represent the original image-matrix. There is loss of data, in the sense that, the original matrix cannot be...
The m-file finds the elimination matrices (and scaling matrices) to reduce any A matrix to the identity matrix using the Gauss-Jordan elimination method without pivoting. Using the matrices gotten it computes the inverse of the A matrix.
Return the optimal path given the adjacency/cost sparse matrix and source/destination nodes.
Run mexme_dijkstra.m to compile mex-files on your own-plateform. Be sure that "mex -setup" have been done at least one.
This utility can be useful when you need to update a sparse matrix values without changing its sparsity pattern.
Since MATLAB uses CSC (Compressed Sparse Column) format for sparse matries, the non-zeroes are stored in an array,...
Table records can be inserted or updated using a list of table field values.
Key Features of Flash SQL: - Delete table records that match a given condition - Retrieve a table field values of records that match a given...
