-homogeneous equations of the solution set X = p + SV is the special solution of the equation, that is, the following theorem is establishedInteresting thing, for the solution is r^2 or r^3 situation, we can add the base vector to describe the relationship between the two sets of solutions geometrically, that is, the non-homogeneous equation of the group of the arbitrary solution can be regarded as its spec
the linear Equation Group general solution, This allows us to directly transform the vector equation into an augmented matrix to solve the problem.Meaning of the span symbol: based on a linear combination of concepts, we remember that span (V1,v2,v3,..., vn) represents a collection of all
Matrix equation:We have previously introduced the linear combination of vectors, the form of X1a1+x2a2+xnan, that we can use to express them with [] formulas. (This expression is sought for convenience and unity of computation), and we give the following definition to give another form of the linear combination of vectors.It can be seen that the right side of the equati
@, if there is no solution to the linear equations, the equations are said to be incompatible (inconsistent).@, if there is at least one solution in a linear equation group, the equations are said to be compatible (consistent).@, the equivalent equations group (equivalent systems).@, definition: If two equations with the same variables have the same set of soluti
certainly has some advantages, like more safe code, better memory management in. net sense and exception handling. however, this strategy wowould have a long development time. I also suspect their efficiency. I have a L-BFGS-based logistic regression solver written C ++, it runs 3 ~ 4 times slower if compiled. net using C ++/CLI. drawing a conclusion from this single case is too assertive. (I used STL and STL is slow in C ++/CLI, in C ++/CLI we 'd be
matrix can be orthogonal diagonalization equivalent to it is a symmetric matrix. \ (a=pdp^{-1}\) can get PCA (machine learning algorithm principal component analysis, diagonalization of covariance matrix (symmetry)) The two-time equation is transformed into a form without cross-multiplication. X=py, \ (A = pdp^{-1}\). For two functions \ (x^{\top}ax\), the |x| = 1, the maximum value is the maximum eigenvalue and the minimum value is the m
descriptions of the same linear transformation (which is different because a different base is selected, i.e. a different coordinate system is selected), then a non-singular matrix p must be found to satisfy the relationship between A and B:A = p-1bpLinear algebra A little bit more familiar to the reader to see, this is the definition of the similarity matrix. Yes, the so-called similarity matrix is a diff
, the linear equations (1) can use the following matrix (2) . In fact, with (2), the linear equations except words that represent unknown numbers (1) are determined, and the words used to represent unknown numbers are of course not substantive. I learned how to use addition and subtraction elimination methods and substitution elimination methods to solve binary and ternary
linear transformation of the two different descriptions (the reason is different because the selection of different bases, that is, the selection of a different coordinate system), you will be able to find a A non-singular matrix P, which enables a and b to satisfy such a relationship: A=P?1BP. Linear algebra A little bit more familiar to the reader to see, this
Linear Algebra is a major branch of Higher Algebra. We know that a single equation is called a linear equation, and the algebra for discussing Line

X_n] acts on a group of vectors to obtain the final result solution vector. 1 x_1 + 2 X_2 = 7 -2 x_1 + 5 X_2 = 4 -5 x_1 + 6 X_2 =-3 Can be viewedA_1= [1,-2,-5] ^ tA_2= [2, 5, 6] ^ tB= [7, 4,-3] ^ t A_1X_1 +A_2X_2 =B A major idea of
open our linear path from the vector space.Influenced by the axiomatic trend of thought, many basic concepts of linear algebra can also be expressed in the language of abstract algebra. Now that we have studied abstract algebra, I will not shy away from references to concep
linear transformation of the different matrix description, that is the Clan brothers, meet do not know, not become a joke. Fortunately, we can find the same linear transformation of the Matrix Brothers One of the properties, that is: if the matrix A and B is the same linear transformation of the two different descriptions (the reason is different because the sel
, R=m because all rows have a main element, after the elimination of a total of 0 rows, the ax=b has an infinite number of solutions.and the number of free variables is n-r, and the 0 space of matrix A is not only 0 vectors.Like what:watermark/2/text/ahr0cdovl2jsb2cuy3nkbi5uzxqvdgvuz3dlaxr3/font/5a6l5l2t/fontsize/400/fill/i0jbqkfcma==/ Dissolve/70/gravity/center ">3, R=m=n.

we are faced with the question of how do we determine the linear correlation for a given m-vector r^n?There is a definition of what kind of algorithm, through the beginning of our definition of linear correlation, we can find that we only need to discuss the vector equation x1v1 + x2v2 + x3v3 +...+XMVM = 0 solution can, this goes back to our previous section int
Linear transformations:As we mentioned earlier, when we discuss the matrix equation ax = b and the vector equation X1a1+x2a2+x3a3+...+xnan = b, we have said that this will echo the rules of matrix multiplication. But here we first introduce a concept of transition-the linear transformation.To investigate the matrix
Label: linear algebra equations Previous Article Describes the solution of AX = 0 and the zero space of matrix, Here we will discuss the solution of Ax = B and the column space of matrix. Ax = 0 is certainly a solution, because the total existence of X is the whole zero vector, making the equations true. While Ax = B does not necessarily have solutions. We need Gaussian elimination elements to determine
