I have to create a matlab matrix that is much bigger that my phisical memory, and i want to take advantage of the sparsity.
I created a sparse matrix in MEX using mxCreateSparse. mxArray *W; W=mxCreateSparse(n*n,n*n,xsize,mxREAL);开发者_运维百科
I wish to do the following in matlab: -I have a text file with the following format: 110.242 120.332 ...
I\'m trying to implement a matrix-vector Multiplication on GPU (using CUDA). In my C++ code (CPU), I load the matrix as a dense matrix, and then I perform the matrix-vector multiplication using CUDA.
I am working with data from neuroimaging and because of the large amount of data, I would like to use sparse matrices for my code (scipy.sparse.lil_matrix or csr_matrix).
I\'m trying to develop a program in C to convert a sparse matrix file into a dense matrix. From what I\'ve read, the best approach would be the开发者_运维问答 use of linked lists but I have no experie
Is it possible to define a sparse matrix in scipy from a function rather than the laying out all the possible values? In the doc\'s I see that a sparse matrix can be created by
I have a NxM matrix and I want to compute the NxN matrix of Euclidean distances between the M points.In my problem, N is about 100,000.As I plan to use this matrix for a k-nearest neighbor algorithm,
for sparse matrices i had put a question about its linked representation. there were two lists to be implemented for a nine zero elements of a 5x8 matrix.....one is the coloumn list and another one is
I\'ve found a qui开发者_运维技巧te good sparse matrix implementation for c# over http://www.blackbeltcoder.com/Articles/algorithms/creating-a-sparse-matrix-in-net.
