## Norm Error Matlab

The condition number of a matrix A is defined as , where A is square and invertible, and p is or one of the other possibilities in Table4.2. http://stackoverflow.com/questions/7743044/relative-error-between-two-matrices Considering the function $f(\epsilon)=\epsilon/(1-\epsilon)$, you can make its Taylor expansion at $0$: $f(\epsilon)=\epsilon+O(\epsilon^2)$. L2 Error Norm See Table4.2 for a summary of norms. Norm Of Error Vector The most obvious generalization of to matrices would appear to be , but this does not have certain important mathematical properties that make deriving error bounds convenient (see section4.2.1).

I am able to prove the inequality using the given information and some algebraic manipulation but the "within O(y^2) accuracy" part I don't get. It represents a potentially different function for each problem. Anti-static wrist strap around your wrist or around your ankle? Errors in matrices may also be measured with norms.

Instruments In most indicating instruments, the accuracy is guaranteed to a certain percentage of full-scale reading. Table 4.2: Vector and matrix norms Vector Matrix one-norm two-norm Frobenius norm |x|F = |x|2 infinity-norm If is an approximation to the exact vector x, we will refer to as Then there is a scalar such that The approximation holds when is much less than 1 (less than .1 will do nicely). The following example illustrates these ideas: so is accurate to 1 decimal digit.
