举个例子,比如说现在有一个变量matrix是一个二维数组,matrix中每一个元素都是一个数字数组。如果你尝试去访问其中的某个数值,你可以这样写:matrix[x][y].这里是一个具体的例子,通过二维数组表示一个乘法表。 //创建一个多维数组 let table = new Array(10); //数组中一共有10行。 for(let i = 0; i ...
第一部分 字典学习以及稀疏表示的概要 字典学习(Dictionary Learning)和稀疏表示(Sparse Representation)在学术界的正式称谓应该是稀疏字典学习(Sparse Dictionary Learning).该算法理论包含两个阶段:字典构建阶段(Dictionary Generate)和利用字典(稀疏的)表示样本阶段(Sparse coding with a precomputed dictionary).这两个阶段...

Serialize an array into bytes. A 1-by-nnumeric matrix of typemxUINT8_CLASSis returned containing the serialized data. The data can be deserialized back into the original representation by callingmwArray::Deserialize(). Example mwArray a(2, 2, mxDOUBLE_CLASS); mwArray b = a.Serialize(); ...
Recently, the field of sparse representation has attracted a great deal of attention from the perspective of target bearing (angle of arrival) estimation. This strategy takes the approach that a target present in a sensor array's field of view may be treated as a sparse signal, e.g. if a...
A framework of demosaicing and superresolution for color filter array (CFA) via residual image reconstruction and sparse representation is presented.Given the intermediate image produced by certain demosaicing and interpolation technique, a residual image between the final reconstruction image and the ...
A method named covariance matrix sparse representation (CMSR) is developed to detect the number and estimate the directions of multiple, simultaneous sources by decomposing the array output covariance matrix under sparsity constraint. In CMSR the covariance matrix elements are aligned to form a new ...

Beginning with a refined covariance matrix, we establish a robust sparse representation framework using a sophisticated 3D redundant dictionary in tandem with COMP-ESP. This enables precise extraction of sparse vectors, revealing accurate off-grid source directions for both correlated and uncorrelated ...
SparseLongArray Attributes RegisterAttribute Remarks 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...
