I don't know what's involved in terms of lists, but it seems to me this is fundamentally important, to respect accepted notation and not give quirky objections and insist on usually unreadable tangles of lists.Īfter all, this matrix layout evolved for both readability and intuitiveness, right? There are direct connections to projections and to mapping onto other basis vectors that come through when standard matrix layout can be used. I wish Mathematica always allowed straightforward matrix and vector multiplications, without behaving in a non-standard way if you have a column vector on the right, for example. Īm I wrong, or isn't this form of term-by-term multiplication when the second vector is actually a vector of basis vectors, a quick way to map onto a new basis? I just wish we could also use the intuitive notation or, even better.

I wouldn't have guessed that you could pass in one 3D vector function, not a list of functions for each coordinate.

Finance, Statistics & Business Analysis Linear Programming : The Simplex Method Initial System and Slack Variables Roughly speaking, the idea of the simplex method is to represent an LP problem as a system of linear equations, and then a certain solu-tion (possessing some properties we will de ne later) of the obtained system would be an optimal solution of the initial LP.
