Machines able to run wgrib2 linux: This is a mandatory compile option for some distributions and is just a good idea. However, the gcc in RH5 doesn't support this option. For other systems, you may have to modify the makefile.

Eventually, outputting the differences between the 2 sets Introduction Here is an example situation: You have CSV comma-separate values files for both years listing each year's attendees. You would like to know which attendees attended the second bash, but not the first.

Environment setup We're off to a great start!

If you're running under Mac OS X, open the Terminal application from the Utilities directory and type python Windows users should follow this article to install it. My recommendation would be to get the latest 2. Once you've got the Python executable running, you should see a line beginning with three greater-than signs.

It will look like this: Once you've seen the interpreter answer back, you can exit it by typing exit and pressing Enter. We'll be using the following example CSV data files all attendee names and emails were randomly generated: Go ahead and download these files to your computer.

Python allows you to open text files such as these and read their contenteither all at once, or line-by-line. In the case of CSV files, we'll make use of a module built-in to Python which will simplify their parsing.

The module in question is called, simply, csv. We will need a few things to get started: Although Python provides you with a number of built-in modules, you need to explicitly declare which modules you'll be using.

This will become our program's first line: We'll open the first attendance CSV file, store a reference to this open file as f and then pass this reference to the csv module. Here's what it would like so far: What do we get in return?

This list should go on and on. Yes, it is the list of attendees from the attendees1. We can see these lists corresponding to rows in the attendees CSV file are made up of three elements, the third being the e-mail address we'd like to use to compare attendees.

In Python, square brackets are used to access an element located at some position "index" in a list. All together, as another example, to print the "2nd" in human-speak element of a list, you would write: Back to our attendee CSV file, to print out the e-mail address of every attendee, we'll modify the code a bit in order to get: Creating lists We were successful in accessing and printing the e-mail address from every row in the CSV file.

Let's now create an empty list object which we will populate with those e-mail addresses.

Save a dictionary of names and arrays into a MATLAB-style.mat file. Scipy / Numpy into MATLAB.

This, again, is to allow us to compare the first year's attendees with the second year's. First things first -- let's create an empty list. An empty list is assigned to a variable by writing the following: Considering the list created above, appending a string to it would look this: We can verify by printing the list object: Modifying the code we've been working on so far gives us this: Well, the code above is only running on the attendees from the first year's party since we're only reading the attendees1.

We should do the same processing i.The csv module implements classes to read and write tabular data in CSV format. It allows programmers to say, “write this data in the format preferred by Excel,” or “read data from this file which was generated by Excel,” without knowing the precise details of the CSV format used by Excel.

You'd load the data into MATLAB as you described (completely independent of using Simulink), then load the data into Simulink from the MATLAB Workspace.

[A,count] = fscanf(___) additionally returns the number of fields that fscanf reads into A. For numeric data, this is the number of values read. For numeric data, this is the number of values read.

You can use this syntax with any of the input arguments of the previous syntaxes. This the second part of the Recurrent Neural Network Tutorial. The first part is here..

Code to follow along is on Github. In this part we will implement a full Recurrent Neural Network from scratch using Python and optimize our implementation using Theano, a library to perform operations on a GPU. The full code is available on Github.
