In Lua, a matrix can be implmented as a multidimensional arrays. As in lua array, data is stored based on indices it is possible to place the elements in a sparse way and it is the way Lua implementation of a matrix works. Since it does not store nil values in Lua, it is ...
矩阵与矩阵计算,其中3个稀疏矩阵采用3-arrays CSR格式存储,为基1索引,具体执行操作为:C = op(A) * B。 其中,A、B、C是采用CSR格式存储的稀疏矩阵。 op(A)根据参数是以下3种情况之一: op(A) = A op(A) = AT op(A) = AH 接口定义 C interface: kml_sparse_status_t kml_sparse_scsrmultcsr(con...
The map function, like forEach doesn't call on the hole, but it will always return the hole in your result. const a = [ undefined, , true ]; const res = a.map(v => typeof v); console.log(res) // [ "undefined", hole × 1, "boolean" ] This map with sparse arrays also...
Here, we experimentally show that such reconstruction also leads to super-resolution in both PA and US imaging with arrays having much less elements than used conventionally (sparse arrays). As a proof of concept, we obtained super-resolution PA and US cross-sectional images of microfluidic ...

Thespraypackage in use Base R has extensive support for multidimensional arrays. Consider a<-array(0,dim=4:12)a[2,2,2,2,2,2,2,2,2]<-17a[3,4,2,2,7,2,3,2,3]<-18 Handlingarequires storage of floating point numbers (of which two are nonzero), represented in an elegant format...
In the provided sample code by Intel (sparse_spmmd.c) you first release the matrix handle and then deallocate associated arrays: if( mkl_sparse_destroy( csrB ) != SPARSE_STATUS_SUCCESS){ printf(" Error after MKL_SPARSE_DESTROY, csrB \n");fflush(0); status = 1;...

Each of the 280 coefficient arrays C was summed as per the Eq. (6) below to produce a vector: $$\begin{aligned} C_{as} = vecc\left( \sum _{i=1}^{7}\sum _{j=1}^{40}\left| C(i,j,.)\right| \right) \end{aligned}$$ (6) where vecc() denotes columnization. \(C^{...
