Diagonal mathematica
WebIf a matrix is diagonalizable, it can be decomposed as , where is nonsingular and is diagonal. This can be used to compute a matrix function by using its power series representation as , and can be computed by simply applying to each of the diagonal elements. Use this method to compute several different matrix functions: WebIn geometry, a diagonal is a line segment joining two vertices of a polygon or polyhedron, when those vertices are not on the same edge. Informally, any sloping line is called diagonal. The word diagonal derives from the …

Web$\begingroup$ +1 Great solution. It may be worth pointing out, though, that the example is not a block-diagonal matrix. By definition, a block … WebIt invokes as many separate Mathematica evaluations as the length of the diagonal. It will unpack packed Real arrays when written like this because it assigns 0 instead of 0.0 . A better solution would explicitly need to check for packed arrays, detect their type (integer or real/complex) and assign the appropriate element.
