Nettet17. sep. 2024 · The product of a matrix A by a vector x will be the linear combination of the columns of A using the components of x as weights. If A is an m × n matrix, then x must be an n -dimensional vector, and the product Ax will be an m -dimensional vector. … NettetHere's a straightforward approach: compute the rank of the matrix that results from removing each of the columns. The columns which, when removed, result in the highest rank are the linearly dependent ones (since removing those does not decrease rank, while removing a linearly independent column does). In R:
