WebMar 24, 2024 · An n×n complex matrix A is called positive definite if R[x^*Ax]>0 (1) for all nonzero complex vectors x in C^n, where x^* denotes the conjugate transpose of the vector x. In the case of a real matrix A, equation (1) reduces to x^(T)Ax>0, (2) where x^(T) denotes the transpose. Positive definite matrices are of both theoretical and computational … WebApr 24, 2024 · The determinant of a matrix is the signed factor by which areas are scaled by this matrix.

WebOct 27, 2015 · I am trying to solve a linear equation in x, where the equation is given by Det [M]==0. The M is a symmetric matrix (dimensions 47x47) with an element equal to x and all other elements are equal to numbers ranging from 1 to 10^4. So, Det [M] is a linear equation in x. I could get a solution for a 11x11 matrix using 'Solve', but when the ... WebOct 1, 2024 · You should be able to produce a new Matrix (having the same determinant) whose diagonal entries are: 2, (i+1)/i, i=2..n. The determinant is thus a conveniently telescoping product. ... An algorithm on mathematica to calculate the determinant of a n*n matrix: 4. Alternative ways to calculate the determinant of a matrix in R. 0. WebI believe if I set a = 1, e = 2, and i = 3 (all other variables 0 ), the determinant of the first matrix is 6, and then for the second matrix is 12. These were arbitrary variable initializations and can be any number. The relationship between the two (a scalar multiple of 2) will be the same irrespective of what I set the variables to. the true story of spit macphee
