This matrix uses 800-megabytes of memory. Convert the matrix to sparse storage. S = sparse(A); whosS Name Size Bytes Class Attributes S 10000x10000 240008 double sparse In sparse form, the same matrix uses roughly 0.25-megabytes of memory. In this case, you can avoid full storage complete...
1. 有些学校以 Turbo C 为环境讲 C 语言,只是 Turbo C 的环境实在太老了,复制粘贴都很不方便。 2. 有些学校直接拿 VC 来讲 C 语言,因为 VC 的编辑和调试环境都很优秀,并且 VC 有适合教学的免费版本。可惜在 VC 下只能做一些文字性的练习题,想画条直线画个圆都很难,还要注册窗口类、建消息循环等等,...

Use mxCreateSparseLogicalMatrix to create an m-by-n mxArray of mxLogical elements. mxCreateSparseLogicalMatrix initializes each element in the array to logical 0. Call mxDestroyArray when you finish using the mxArray. mxDestroyArray deallocates the mxArray and its elements. ...
