This is called an overdetermined linear system because, in general, the system has more equations to satisfy than the variables allow. The complementary underdetermined case m < n turns up less ...

WebAll the things you would do in python with "linspace, arrange, logspace", are implemented directly inside the "range" function in Julia. Note that that gives you n+1 points. e.g. 0: (1-0)/2:1 = [0.0, 0.5, 1.0] . Nice, thanks for noting that, with the dividing n on the denominator, the number of points would be n+1 ! http://www.jlhub.com/julia/manual/en/function/ones
