Player Pro only kills it.
Mikel, If you will read my tutorial you will see how to name your packages and have access to them. I don't feel like reproducing all of it right here. But also you will have to include the second argument in the BeginPackage statement that declares...
In regular Mathematica one would normally use Input cells. Code cells are used in package.m files. They contain the code for the routines, not Input cells. You can switch between the two cell types by selecting the right hand cell bracket and...
Chemical stoichiometry is really a kind of homological algebra. I was able to implement at least a simple form of this using John Browne's Grassmann algebra code. There is a chain complex going from moieties (atoms or unbroken chemical units) to...
I believe that the Mathematica graphics paradigm could be much improved. I see as a problem that it has become more and more filled with special types of unrelated plots. In an effort to add flexibility to these plots I feel they have been encumbered...
You can find some examples and pictures of these items in Wikipedia or perhaps other places on the web. You could look up Grad, Div, Curl, VectorPlot, VectorPlot3D, ContourPlot and ContourPlot3D in Mathematica Documentation but you will probably not...
As long as we're talking about RowReduce I would like to mention a deficiency. It would be very nice if the row reduction, or perhaps more correctly the pivot elements, could be confined to a contiguous block of elements in the matrix. The pivot...
The following is an example of using an Association to store information, definitions, routines and even a dynamic display for a mathematical object. A reader can implement and use the routines simply by taking the Values of the Association. This...
I wasn't thinking so much of the specific PISA test, which I know nothing about, but the whole process of cramming facts and taking tests. Why not write a literate Mathematica notebook exploring some topic and be judged on the quality of that? Do...
I would like to additionally point out that if there is a Function name in a text or Section cell and one places the cursor in or just after it, or if it is selected, then the F1 key or the "Find selected Function" item in the Help menu will bring up...
