WebTo get the matrix in the correct form, we can 1) swap rows, 2) multiply rows by a non-zero constant, or 3) replace a row with the product of another row times a constant added to the row to be replaced. Here is an example: Solve the following system of equations : . Find the first non-zero entry in the first column; this is the pivot. WebSolution: The reduction of to row-echelon form is . Because this row-echelon matrix has two leading s, rank . Suppose that rank , where is a matrix with rows and columns. Then because the leading s lie in different rows, and because the leading s lie in different columns. Moreover, the rank has a useful application to equations. WebMatrix Rank.
