Definition 1 The rank of a matrix A denoted rank(A) is the maximum number of independent rows in A.. Observation Here we view each row in matrix A as a row vector. Thus rank(A) the dimension of the span of the set of rows in A (see Definition 2 of Linear Independent Vectors).For an m n matrix A clearly rank(A) m.. It turns out that the rank of a matrix A is also equal to the Oct 26 2016 Definition 1 A matrix A has a Cholesky Decomposition if there is a lower triangular matrix L all whose diagonal elements are positive such that A LL T. Theorem 1 Every positive definite matrix A has a Cholesky Decomposition and we can construct this decomposition Outside of VBA Excels single most powerful feature is PowerPivot which is an official MS add-in for Excel that takes pivoting not just to the next level but to a whole other world.

It contains element of the same type. The data types can be logical integer double character complex or raw.

Also note that if z is a zoo series then lag(z 0-1) is a two column zoo series with the original series and a lagged series. Also coredata(z) will return just the data part of a zoo series and as.data.frame(z) will return a data frame with the data part of z as the column contents.In linear algebra an eigenvector or characteristic vector of a linear transformation is a non-zero vector that changes by only a scalar factor when that linear transformation is applied to it. More formally if T is a linear transformation from a vector graphice V over a field F into itself and v is a vector in V that is not the zero vector then v is an eigenvector of T if T(v) is a scalar
