Power of a matrixIt is shown that if P 1 and P 2 are orthogonal projectors, then a product having P 1 and P 2 as its factors is equal to another such product if and only if P 1 and P 2 commute, in which case all products involving P 1 and P 2 reduce to the orthogonal ...
An orthogonal matrix {eq}X {/eq} has the property that {eq}X^tX=I {/eq}. Prove that {eq}X^tAX \text{ and } A {/eq} have the same characteristic polynomial. Characteristic Polynomials of Matrices First we are given an orthogonal matr...
The second property can be expressed in terms of the stiffness matrix as: [70]ϕnTKϕm=0(m≠n) which states that the mode shapes are orthogonal to the stiffness matrix. Although not necessarily true, for the sake of computational convenience it is further assumed that the mode shapes ...

* - Calculating a 3x3 `orientation` matrix from the resulting three orthogonal unit vectors * - Using `position` from the `frame_origin` property as the `position` of the resulting frame * - These steps yield an `orientation` + `position`: the basis for an OpenSim frame * * `StationDe...
Let D(v,k,λ1,λ2,m,n) be a SGDD with the dual property, R be the quotient matrix of D, and Rext be the extended quotient matrix. If p is a prime such that p∣(k2−vλ2), then the extended code Cext over Fp is self-orthogonal with respect to ψ. Proof Let x and y ...
which means that the value of θ that maximizes fY (·) depends on S. If the MLE is unique, the MLE of θ must be a function of S. ▪ Example 6.2.3 Consider the problem from Example 6.2.2. Rewrite the model as Y = Xα + E where the n× 1 matrix X = 1n and the n× ...
