SpletThe graph of a linear equation in one variable x forms a vertical line that is parallel to the y-axis and vice-versa, whereas, the graph of a linear equation in two variables x and y forms a straight line. Let us graph a linear equation in two variables with the help of the following example. Example: Plot a graph for a linear equation in two variables, x - 2y = 2. SpletS = svd (A) returns the singular values of matrix A in descending order. example [U,S,V] = svd (A) performs a singular value decomposition of matrix A, such that A = U*S*V'. example [ ___ ] = svd (A,"econ") produces an economy-size decomposition of A using either of the previous output argument combinations. If A is an m -by- n matrix, then:
