WebIf we are given a matrix for the transformation, then the image is the span of the column vectors. But we do not need all of them in general. A column vector of A is called a pivot column if it contains a leading one after row reduction. The other columns are called redundant columns. The pivot columns of A span the image of A. Proof. WebI'm trying to code up a simple Simplex algorithm, the first step of which is to find a basic feasible solution: Choose a set B of linearly independent columns of A. Set all components of x corresponding to the columns not in B to zero. Solve the m resulting equations to determine the components of x. These are the basic variables.
