Block diagonal matrix mathematica
WebSep 2, 2015 · I came across the "SparseArray" command upon my research and it help me create a Tri-Diagonal Matrix, but I am having a hard time manipulating it to get the $-1, 2, -1$ pattern I am looking for. mat = SparseArray [ {i_, j_} /; Abs [i - j] <= 1 :> 1, {10, 10}]; mat // MatrixForm Above is the command I used for a $10 \times 10$ matrix. WebJul 29, 2011 · Inspired by Mike Bantegui's question on constructing a matrix defined as a recurrence relation, I wonder if there is any general guidance that could be given on setting up large block matrices in the least computation time. In my experience, constructing the blocks and then putting them together can be quite inefficient (thus my answer was …

WebDiagonal Diagonal Diagonal [ m] gives the list of elements on the leading diagonal of the matrix m. Diagonal [ m, k] gives the elements on the k diagonal of m. Details Examples open all Basic Examples (4) Give the diagonal elements of a matrix: In [1]:= In [2]:= Out [2]= Obtain the superdiagonal: In [1]:= Out [1]= Obtain the subdiagonal: In [1]:= WebA package that translates between Polchinski's theta-function conventions and Mathematica's. BlockInverse.nb A short snippet of code that teaches Mathematica to invert a diagonal (or block-diagonal) matrix by inverting each diagonal entry (or block) separately. For algebraic matrices this results in simpler output, and for numerical ones it ...

WebNov 11, 2010 · newMainDiagList = Flatten@Array [Subscript [new, ##] &, {1, 4}] I know it is easy to change the main diagonal to a given value using ReplacePart. For example: ReplacePart [mat, {i_, i_} -> 0] I'd also like not to be restricted to the main diagonal (in the same way that Band is not so restricted with SparseArray) (The method I use at the …
Web0. First we set M ~ for the matrix obtained by replacing all non-zero elements by 1. Start with a vector v ~ 1 having exactly one coordinate equal to 1 and all other coordinates zero. Consider v 2 = v 1 + M ~ v 1 and define v ~ 2 by replacing all non-zero elements (which are in fact strictly positive integers) of v 2 with 1 . WebA block tridiagonal matrix is another special block matrix, which is just like the block diagonal matrix a square matrix, having square matrices (blocks) in the lower diagonal, main diagonal and upper diagonal, with all other blocks being zero matrices. It is essentially a tridiagonal matrix but has submatrices in places of scalars.
WebAnd a square matrix is diagonalizable if and only if its minimal polynomial splits (which is automatic in $\mathbb{C}$ of course) with only simple roots. In other words, as pointed …
WebThe components of a basis matrix are organized into blocks with numTspins as the number of blocks on a side. block - The ij block is a matrix with 2si +1 rows and 2tj +1 columns where si is the ith T-spin and tj is the jth T-spin dimREP - the number of states in the (p,q) irrep (multiplet). n0 - number related to size of the caps of the T-spin ... frontline meaning in englishWebJordanDecomposition JordanDecomposition.
