The rank of a matrix A is the dimension of the vector space formed by its columns in linear algebra. In this article we will learn some useful information about this.
Answer to: Find the rank of A = \begin{pmatrix}2 &1& -4\\ -4& -1& 6\\ -2& 2& -2\end{pmatrix} and explain why A is not invertible. By signing up,...
Their ranks are equal:rank(M)=rank(N). Answer and Explanation:1 Ifais an invertible matrix, then {eq}\begin{align*} a^{-1}(ab)a&=(a^{-1}a)(ba)\&=I_n ba&&\text{(by the definition of an invertible... Lea...

Meanis the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers. Mean = (Sum of all the observations/Total number of observations) Example: What is the mean of 2, 4, 6, 8 and 10?
Find an invertible n \times n matrix a and an n \times n matrix b such that \mathrm{rank}(ab) \neq \mathrm{rank}(ba), or explain why such matrices cannot exist. The following matrix is not invertible. What should...

So all varchar's are converted to string type respective of their size. And max length of string type is 2,147,483,647.So you cannot get the actual size defined in database.You can get the length of the characters in DataSet columns (if it is string type) but the value will va...
Overreliance on equilibrium-based methods for measuring potency, such as concentration response or IC50, can mislead researchers as to the rank order of covalent compounds with respect to potency The irreversible nature of covalent inhibition has the effect that such methods will give different results...
