👉 In mathematics, unsagging is a method used in linear algebra to find the solution of a system of linear equations by first finding an orthogonal basis of the space spanned by the rows of the matrix. This process is known as Gram-Schmidt orthonormalization. The term "unsagging" refers to the step where the rows of the original matrix are normalized, so that the columns of the resulting matrix are orthonormal (orthonormalized). The goal here is to
