sparse-arrayA Clojure library designed to manipulate sparse arrays - multi-dimensional spaces accessed by indices, but containing arbitrary values rather than just numbers. For sparse spaces which contain numbers only, you're better to use a sparse matrix library, for example clojure.core.matrix.Arb...

MATLAB Online에서 열기 Hi, I met a problem dealing with very large scale data. My server's limit is: >> [str,maxsize]=computer str = GLNXA64 maxsize = 2.8147e+14 And I define an array like ones(3^N, 3^N, N+1, 1000,'uint16') where N=13. ...
Sparse Array Grating Lobes Phased arrays can be configured to have spacing between elements of greater than 1/2 wavelength to reduce hardware costs while still meeting functional requirements for the specified task. These sparse arrays will have grating lobes in the array response. The Phased Array...
