Jacobian Matrix
Jacobian Matrix
A matrix with entries representing all the first-order partial derivatives of a vector-valued function, where each row corresponds to a component of the output and each column corresponds to a variable in the input.
Jacobian Determinant
Jacobian Determinant
The determinant of the Jacobian matrix, calculated when the matrix is square (same number of rows and columns).
Entry of the Jacobian Matrix
Entry of the Jacobian Matrix
The (i,j)th entry of the Jacobian matrix is the partial derivative of the i-th component of the output function with respect to the j-th input variable.
