In fact, layout animation is also implemented through the matrix class.Matrix computing The matrix class also provides a direct matrix calculation method. Matrix A = new matrix () is equivalent to creating a matrix of units. A. Set (B) is assigned A = B; A. preconcat (B), equivalent to the premultiplication, that i

very large, especially when data is obtained from a remote database and sent over the network. In this case, you do not need to read all the data. When a largeobject object is created, it creates an object "shell" instead of reading all the data from the disk. When a data is needed, the data is retrieved from the database. The implementation method of this "demand-paged" object initialization is Class largeobject { Lazy expression evaluation) Template A data structure should be established to

Title: n matrix multiplication, to find the least number of multiply operations and how to combineSuppose that matrix A is r1*r2 and matrix B is R2*R3, so m=a*b=r1*r2*r3. When multiple matrices are multiplied, the number of operations is different when the matrix is combined in different ways.Example: M=M1 * M2 * M3 * M4[5*20] [20*50] [50*1] [1*100]((m1*m2) *m3) *m4=5000+250+500=5750and M1* (m2* (
