Four-dimensional mapping: This problem can be achieved with the slice command:%%%=================================%%%Clear All[x, Y, z] = Meshgrid (0:.5:10,0:.5:10,0:.5:10);c = x.^2+y.^2+z.^2;xs = [0,2,4,6,8,10];YS = [4];ZS = [6]; % Xs,ys,zs can determine the form and position of the slice, Helpslice can understand its specific meaningSlice (X,y,z,c,xs,ys,zs)ColorMap HSV Of course, as long as Doc Surf, you will find, in fact, the surf command has its own color command:A simple example is as fo

Row Share (RS)This lock, also called a subshare table lock (SS), indicates then the transaction holding the lock on the table have locked Rows in the table and intends to update them. A row share lock is the least restrictive mode of table lock, offering the highest degree of concurrency for a table.Row Exclusive Table Lock (RX) This lock, also called a subexclusive table lock (SX), generally indicates, the transaction holding the lock has Updat Ed ta

　　A brain puzzle worth writing!At first, there was no thought, and it was only after reading the solution.Considering the and representation of A and b as coordinates, then the point that may be the answer must be the point in the lower convex packet, so that the optimization enumeration guarantees efficiency.However, it is not known exactly which points are the points in the convex package, but we know that the boundary of two points (a minimum of B minimum) must be on the convex hull, if it is
