You can verify that by calling null(full(A)) on an example matrix (I used Nx = Ny = 10, dx = dy = 0.1). This showed that there is a null space of dimension one, and the vector in that null space had all elements of equal value.
Well, sometimes data can be massive and complicated, and it's hard to make sense of it all. SVD helps us simplify the data and find the most essential parts to understand it better. What is Singular Decomposition Value Singular Value Decomposition is a way to factor a matrix A into three...
The rank of matrix A is the dimension of the vector space formed its columns in linear algebra. In this article we will learn some useful information about rank of a matrix including its properties. Check the definition, examples and methods to find the rank of the matrix along with solved...
Find the eigenvector of the following matrix. -1 &-1 1 & 1 How to tell if the matrix has eigenvalue 0? Let B=\begin{bmatrix} 1 & -2 & 0 & 4\1 & 2 & 3 & -3\-1 & 1 & 4 & -1\2 & 0 & 1 & 0 \end{bmatrix}, Determine whether each vector is an eigenvector of...
How to determine if a matrix is singular or non-singular? Determinants: First we need to understand the determinant of a matrix to understand the singular or {eq}a_{ij} {/eq} denotes the element of {eq}i^{th} {/eq} row and {eq}j^{th} {/eq} column ...
A singular matrix is a square matrix (one that has a number of rows equal to the number of columns) that has no inverse. That is, if A is a singular matrix, there is no matrix B such that A*B = I, the identity matrix.
If I am not wrong ARPACK uses implicitly restarted Lanczos Bidiagonalisation method for finding eigenvalues which in turn can be used to find singular values from the augmented matrix C I was trying to get smallest singular value of A of size 1.5x10^6 x 1.5x10^6 (sparse with nnz=7.5x10^...

Square matrices have special properties that set them apart from other matrices. A square matrix has the same number of rows and columns. Singular matrices are unique and cannot be multiplied by any other matrix to get the identity matrix.
Are there any values of b for which this matrix will be indefinite? For a given matrix A , does x^T A x 0, \text{ for any } x imply that A is positive definite? For the matrix A below, find a value of k. Let n be a positive integer. Find A to the n when A is th...
