Both the original problem and the algorithm used to solve that problem can be 'well-conditioned' or 'ill-conditioned', and any combination is possible.

Some classes of alternative methods are: Three central concepts in this analysis are: Eigenvectors are vectors that multiply a square matrix and remain parallel to the original matrix, the corresponding Eigenvalue is the scalar the represents the principal value of the matrix (for example principal stresses, stretches and vibrational displacements). University of Michigan Department of Mechanical Engineering January 10, 2005 As you can tell, this page is going to be extensive, but it will give you many tools to help you solve problems.As a side note, I feel that many engineering students are never introduced, formally, toThis page is representative of what I believe to be the most effective and common methods of solving problems (I like avoiding BS).What's the point of using matrices?

>> Extrapolation methods: theory and practice. As in the rectangular and trapezoidal integration approximations, if the step size is minimized, the error is lessened.For an order two Simpson approximation, the following formula may be used:Derivatives may be viewed as the slope between corresponding points in a function (1D case).

We choose a step size It costs more time to solve this equation than explicit methods; this cost must be taken into consideration when one selects the method to use. and solve the resulting system of linear equations.

The goal is to get the [A] Matrix into a upper or lower Well, this method is called naive because it does not precondition the matrix my pivoting row or columns, it also doesn't allow for 'selective harvesting' or eliminating of individual entries of [A] to make our life easier. The algorithm might return any number in that range with an error less than 0.2. Once an error is generated, it will generally propagate through the calculation. The 'solved variables' represent the solution to our problem.
