/MIRROR/GM0 this provider, which represents disk mirroring or duplex. Consumer-This entity receives I/O requests. In the case of mirror/duplex, this refers to the two-piece hard drive. I used two data cables to connect two IDE hard drives respectively, get/dev/ad0 and/dev/ad2. Metadata (metadata)--in different RAID, it includes the array members and their size, location, logical disk and partition description and the current state of the disk array.

); }; gets the specified element We have two ways to get the matrix element. Array Method Because the mat actually holds the data as an array, the data looks like this: R00 G00 B00 A00 R01 G01 B01 A01 ... r0n g0n b0n a0n R10 G10 B10 A10 R11 G11 B11 A11 ... r1n g1n b1n a1n ...... Rm0 Gm0 Bm0 Am0 Rm1 Gm1 Bm1 Am1 ... RMN Gmn Bmn Amn Where capital R, G, B, and a represent the values of each channel, and the subscript first represents the li

... r1n g1n b1n a1n ...... Rm0 Gm0 Bm0 Am0 Rm1 Gm1 Bm1 Am1 ... RMN Gmn Bmn Amn Where capital R, G, B, and a represent the values of each channel, and the subscript first represents the line number, and the second represents the column number. That is, line K, the G-Channel value of column J is gkj. We can easily get to a mat type of mat, the K line, each element of the J-column Pixel is: Rkj = mat.data[(k * Mat.col + j) * 4 + 0] Gkj = mat.data[

That is, the k row, and th
