Maximum elements fromAorB, returned as a scalar, vector, matrix, multidimensional array, table, or timetable. The size ofCis determined by implicit expansion of the dimensions ofAandB. For more information, see
The rank of a matrixAis computed as the number of singular values that are larger than a tolerance. By default, the tolerance ismax(size(A))*eps(norm(A)). However, you can specify a different tolerance with the commandrank(A,tol). ...

其中,“^”表示矩阵的幂运算,例如A是一个方阵,那么A ^ 3等价于A*A*A;“.^”表示对矩阵中的每一个元素分别进行乘方计算,例如A .^ 0.5表示对矩阵A中的每一个元素开根号,等价于sqrt(A)。 特别地,如果A是一个可逆的方阵,那么A^(-1)可用来计算A的逆矩阵(inverse matrix)。另外,MATLAB中的inv函数也可以...

n= norm(X,p)returns thep-norm of matrixX, wherepis1,2, orInf: Ifp = 1, thennis themaximum absolute column sumof the matrix. Ifp = 2, thennis approximatelymax(svd(X)). This value is equivalent tonorm(X). Ifp = Inf, thennis themaximum absolute row sumof the matrix. ...
// Given a NxN matrix A and a Nx1 vector b, generate a Nx1 vector x// such that Ax = b./// Use this to get a hyperplane for a given set of points.// Example.// Given three points (-1, 1, 2), (2, 0, -3), and (5, 1, -2).(这里就是我们的extreme point)// The...
Thecondition number for inversionof a matrix measures the sensitivity of the solution of a system of linear equations to errors in the data. It gives an indication of the accuracy of the results from matrix inversion and the linear equation solution. For example, the 2-norm condition number of...
