Is it possible for a function to have a negative semidefinite Hessian matrix at a critical point?
Yes, it is possible for a function to have a negative semidefinite Hessian matrix at a critical point.
How can the negative definite Hessian matrix be utilized to determine the concavity of a function?
The negative definite Hessian matrix can be used to determine the concavity of a function by checking the signs of its eigenvalues. If all eigenvalues are negative, the function is concave.
What is a weakness associated with a SWOT matrix?

Can someone help find the determinant of this 5x5 matrix?
sorry i didnt know how to type the matrix out basically the 5x5 matrix is... 1 2 5 0 1 2 3 7 1 9 1 2 3 0 3 0 0 1 0 0 3 2 -4 0 1 i understand that the 4th row/column is best to delete. but what do i do from here? please show step by step if you can :)

What is the Hessian Matrix used for?
Hessian matrix are used in large scale extension problems within Newton type approach. The Hessian matrix is a square matrix of second partial derivatives of a function.
How do you find a negative matrix in algebra?
For example, if you have [ -4 1 0 3] as your matrix, it would be negative 4. Whatever negative number is in your matrix is your answer.
What is the formula of bordered Hessian matrix?
The bordered hessian matrix is used for fulfilling the second-order conditions for a maximum/minimum of a function of real variables subject to a constraint. The first row and first column of the bordered hessian correspond to the derivatives of the constraint whereas the other entries correspond to the second and cross partial derivatives of the real-valued function. Other than the bordered entries, the main diagonal of the sub matrix consists of entries for the second partial derivatives. All other entries of the sub matrix off of the main diagonal correspond to all combinations of cross partials. Evaluating the determinant of the bordered hessian will allow one to determine if the function attains its maximum or minimum at the stationary points, which by the way are limited in the fact that they must both satisfy the gradient equations and the constraint.
What is density matrix in quantum mechanics?
It is a Hermitian positive-semidefinite matrix of trace one that describes the statistical state of a quantum system. Hermitian matrix is defined as A=A^(dagger). Meaning that NxN matrix A is equal to it's transposed complex conjugate. Trace is defined as adding all the terms on the diagonal.
Is it possible to multiply a 3x2 matrix and a 2x3 matrix?
Yes, the result is a 3x3 matrix
How do you make a matrix negative?
Multiply -1 by every entry in the matrix. (Flip the signs.)
Is it possible to multiply a 2 X 2 matrix and a 2 X 3 matrix?
Yes it is possible. The resulting matrix would be of the 2x3 order.
Is there a matrix 4?
no (previous answer said no) i will say it is possible that there is going to be a matrix 4, this is because sophia stewart now has the copyrights for the matrix franchise, and she plans to make a matrix 4 movie.
What is a matrix and a scalar?
A matrix and a scalar is a matrix. S + M1 = M2. A scalar is a real number whose square is positive. A matrix is an array of numbers, some of which are scalars and others are vectors, square of the number is negative. A matrix can be a quaternion, the sum of a scalars and three vectors.
What is the smallest 4x4?
A 4x4 matrix with all elements set to zero is the smallest possible 4x4 matrix.
