Conditioning of the matrix

WebA pricing matrix is an array that specifies conditions and results. The array contains rows and columns. Condition columns specify the condition to test, such as Customer Size equals Small. Result columns specify what to do when the condition is true, such as use the Corporate Segment. Each row specifies a separate condition and result. WebCondition number of a matrix is the ratio of the largest singular value of that matrix to the smallest singular value. The P-norm condition number of the matrix A is defined as …

Determining the number of rows or columns of a lower triangular matrix …

For example, the condition number associated with the linear equation Ax = b gives a bound on how inaccurate the solution x will be after approximation. Note that this is before the effects of round-off error are taken into account; conditioning is a property of the matrix, not the algorithm or floating-point accuracy of the computer used to solve the corresponding system. In particular, one should think of the condition number as being (very roughly) the rate at which the solution x will … WebIn linear algebra and numerical analysis, a preconditioner of a matrix is a matrix such that has a smaller condition number than .
