How many pivot columns must a 7x5 matrix have

WebSuch matrix A A A has 5 columns, and all 5 of them \textit{all 5 of them} all 5 of them have to be pivot columns. If there is a case where not all 5 of them are pivot columns, a free variable would exist in equation A x = 0 A\textbf{x}=0 A x = 0 , and this would imply linear dependence of the columns of A A A . WebTo produce a mesh plot of a function of two variables, say z = f(x, y), we must first generate the X and Y matrices which consist of repeated rows and columns over the range of the variables x and y. We can generate the matrices X and Y with the [X, Y]2mesh- grid(x,y) function which creates the matrix X whose rows are copies of the vector x, and the …
