The data structure in which the sparse matrix is encoded may be outputted. The data structure may include the first array.K・斯特劳斯J・福韦尔斯K・奥夫恰罗夫
whose ith element is the size of the ith dimension. Items are undefined. Item Retrieve(A, i) ::= if (i ∈ index) return the item associated with index value i in array A else return error. Array Store(A, i, x) ::= if (i ∈ index) return an array that is identical to array...
The operation of the index is enhanced by the use of data compression and the use of a sparse array bit map to represent the record associated with each field. The index structure within the data base allows each index variable to identify data by means of the index variables inde- pendent...
SparseLongArrays map integers to longs. Unlike a normal array of longs, there can be gaps in the indices. It is intended to be more memory efficient than using a HashMap to map Integers to Longs, both because it avoids auto-boxing keys and values and its data structure doesn't rely on...

In v3.4, the following features are supported for sparse arrays: Creation for sparse arrays. From 3 (data, row, column) sparse host or device memory vectors. From 3 (data, row, column) sparse af::arrays. From dense af::array.
cols(number of columns inb)columnsldb ldb Specifies the leading dimension of matrixb. Output Parameters x Overwritten by the updated matrixy. Return Values SPARSE_STATUS_SUCCESS The operation was successful. SPARSE_STATUS_NOT_INITIALIZED The routine encountered an empty handle or matrix array. ...
For each subject, this resulted in \(40 \times 7\) (=280) sample models with a \((segment \times video \times lag)\) coefficient array for each model. Each of the 280 coefficient arrays C was summed as per the Eq. (6) below to produce a vector: $$\begin{aligned} C_{as} =...
