3 4 linear dimensions

Transformation: If linear transformation exists, it is called inverse transformation = Polynomial of linear transformation: And specify Note: 1) also known as the unit transformation, its matrix is represented as the unit matrix; 2) the corresponding matrix is represented as a zero matrix; 3) Like the product of a matrix, the product of

[Android] Chapter 3 (3) LinearLayout (linear layout) and linearlayout Category: C #, Android, VS2015; Created on:I. Introduction LinearLayout stacks components in the container one by one horizontally or vertically (without overlap ). This layout is very similar to the StackPanel control of WPF. It also sets whether the direction of the layout is vertical or hori

§ 4 spatial Linear Equation General equation of a Spatial Straight Line: The Spatial Straight line can be regarded as the intersection of two planes. In fact, if the plane and equation of the two intersections are : : Then, the coordinates of any point on the Spatial Straight Line satisfy both the plane equations, that is, the equations must be satisfied. (3.4-1) In turn, if a point is not on a straight lin

02-Linear Structure 4 Pop Sequence (25 min)Given a stack which can keepM numbers at the most. Pushnnumbers in the order of 1, 2, 3, ..., nand pop randomly. You were supposed to tell if a given sequence of numbers is a possible pop sequence of the stack. For example, If mis 5 and nis 7, we can obtain 1, 2, 3,

Section 5 of Matrix In this section, we will introduce a commonly used method for processing matrices with higher levels, that is, matrix blocks. sometimes, we regard a large matrix as composed of small matrices, just as the matrix is composed of numbers. especially in operations, these small matrices are processed as numbers. this is the so-called matrix block. To illustrate this method, let's look at an example. , Indicating the level unit matrix, and . In the matrix Medium, . During computi

Some of the theoretical, mathematical, and convex optimization theories involved can be consulted: Why is Newton's method less iterative than the gradient descent method in solving the optimization problem? and the gradient-Newton-quasi-Newton optimization algorithm and its implementation 4, on the last article mentioned in the question, why the logical regression algorithm and the least squares of the final formula of
