Mathematica 7 Notebook In Mathematica 10 Code And Often

When people tell me that Mathematica isn’t fast enough, I usually ask to see the offending code and often find that the problem isn’t a lack in Mathematica‘s performance, but sub-optimal use of Mathematica. Developed by the Australian Mathematical Sciences Institute (AMSI), ICE-EM Mathematics. ICE-EM Mathematics Third Edition is designed to develop a strong foundation in mathematics for every student in Years 5 to 10/10A, and now offers a new level of digital support for teaching, learning, assessment and reporting. Designed to foster understanding and mastery of mathematics in every student.

The notebook will freeze for 30 secs or so, and the window will report 'not. Specifically, the problem seems to occur when typing functions, at the point where the predictive interface will try to suggest an autocomplete for the function. But just change the viewpoint so that.Ive just installed Mathematica 10, on Windows 7, but am having problems with the notebook freezing. It still looks pretty random. Mathematica in the Classroom.

Mathematica 7 Notebook In Mathematica 10 How To Do This

If you didn’t think about the consequences of the double recursion, you might be surprised by the 22 seconds it takes to evaluate fib (about the same time it takes the built-in function to calculate all 208,987,639 digits of Fibonacci ).Running the code in the profiler reveals the reason. But the key feature in this context is the profiler that lets you see which lines of code used up the time, and how many times they were called.Take this example, a truly horrible way (computationally speaking) to implement Fibonacci numbers. First it lets you debug and organize large code projects better, and having clean, organized code should make it easier to write good code. That’s great when you just need to get a quick answer, but it will also let you get away with less than optimal solutions without realizing it.Workbench helps in several ways. Specifying such details might be comparatively fiddly, but staying within Flatten to do the whole flattening job turns out to be nearly 4 times faster than re-implementing that sub-feature yourself.So remember—do a search in the Help menu before you implement anything.Mathematica can be quite forgiving of some kinds of programming mistakes—it will proceed happily in symbolic mode if you forget to initialize a variable at the right point and doesn’t care about recursion or unexpected data types. If I have a list of a million 2×2 matrices that I want to turn into a list of a million flat lists of 4 elements, the conceptually easiest way might be to Map the basic Flatten operation down the list of them.But Flatten knows how to do this whole task on its own when you specify that levels 2 and 3 of the data structure should be merged and level 1 be left alone.

Here it is rescuing the program that I used to illustrate tip 3. But if the possible input set is constrained, this can really help. You are trading speed for memory here, so it isn’t appropriate if your function is likely to be called for a huge number of values, but rarely the same ones twice. The Mathematica construct that you will want to know is this:It saves the result of calling f on any value, so that if it is called again on the same value, Mathematica will not need to work it out again. Remember values that you will need in the future.This is good programming advice in any language.

Your Mathematica comes with four compute kernels, and you can scale up with grid Mathematica if you have access to additional CPU power. There is some overhead for sending the task and retrieving the result, so there is a trade-off of time gained versus time lost. Each of these automatically takes care of communication, worker management, and collection of results. But for other operations, or if you want to parallelize over remote hardware, you can use the built-in parallel programming constructs.There is a collection of tools for this, but for very independent tasks, you can get quite a long way with just ParallelTable, ParallelMap, and ParallelTry. Looking up previous results prevents the need to repeatedly recurse down to fib.An increasing number of Mathematica operations will automatically parallelize over local cores (most linear algebra, image processing, and statistics), and, as we have seen, so does Compile if manually requested.

Use Sow and Reap to accumulate large amounts of data (not AppendTo).Because of the flexibility of Mathematica data structures, AppendTo can’t assume that you will be appending a number, because you might equally append a document or a sound or an image. Unless one of the built-in CUDA-optimized functions happens to do what you want, you will need to do a little work, but the CUDALink and OpenCLLink tools automate a lot of the messy details for you.7. Think about CUDALink and OpenCLLink.If you have GPU hardware, there are some really fast things you can do with massive parallelization. For example, you could send a set of parallel tasks to remote hardware, each of which compiles and runs in C or on a GPU.6.5. More CPUs would give a better speedup.Anything that Mathematica can do, it can also do in parallel.

In my experience, Block and Module are interchangeable in at least 95% of code that I write, but Block is usually faster, and in some cases With (effectively Block with the variables in a read-only state) is faster still.Pattern matching is great. The following are equivalent:Block, With, and Module are all localization constructs with slightly different properties. Sow throws out the values that you want to accumulate, and Reap collects them and builds a data object once at the end. (And the construct data=Append is the same as AppendTo.)Instead use Sow and Reap. This makes it progressively slower as the data accumulates.
