WebMar 26, 2024 · Linear independence means exactly what it sounds like, vectors of a set that cannot be expressed as a linear combination of the other vectors. When vectors are in row form, this is found by performing operations on the rows until we have reduced the matrix to vectors that cannot be expressed as linear combinations of each other. WebThe linear dependency of a sequence of vectors does not depend of the order of the terms in the sequence. This allows defining linear independence for a finite set of vectors: A finite …
WebJan 24, 2016 · Sidenote: The number of rows with all zeros in R R E F ( A) tell only how many rows are independent/dependent (unless it is a square matrix, then the number of (in)dependent rows/columns will be the same) Looking at the leading 1's is much more helpful in determining linear dependence.

WebApr 11, 2013 · Add a comment. 1. Another way to check that m row vectors are linearly independent, when put in a matrix M of size mxn, is to compute. det (M * M^T) i.e. the determinant of a mxm square matrix. It will be zero if and only if M has some dependent rows. However Gaussian elimination should be in general faster.
WebIf none of these vectors can be expressed as a linear combination of the other two, then the vectors are independent; otherwise, they are dependent.
