Function Plotter

This script allows normal functions to be attached to a 'ThunkSpace' which causes the function to be lazily evaluated when the thunk is referenced. It is just an experiment using closures and descriptors to try and change python function call syntax.

This script contains a function, "rename_members", which takes an object, and two strings describing variable naming conventions (e.g. "allcamel", "underscores", etc). It translates attribute names on the given object from the first naming convention to the second (it doesn't delete the original...

This script returns a tuple (cls,self,method), where:  -  cls is the class in wich you can find the definition of the method from which this function is called;  -  self is the instance passed as first argument to the method from which this function is called;  -  method is the unbound...

This script contains a simple, easy to use wrapper function for doing quick tests of your functions using the timeit module.The timeit module provides an easy way of testing the performance of your Python code by running it in many iterations and averaging the timings. However it is not very...

This script is a groupby function for arrays. Given a list of arrays and a `key` function, it will group each array based on the value of `key(args[0])`. The returned arrays will be two dimensional. The size of the first dimension is equal to the number of groups, and the size of the second...

PHP_FunctionCallTracer creates a function calls debug trace. Functions arguments, returned parameters and watched variables are reported in the same section. Traced variables can be processed by provided user functions for displaying purposes.

This simple function will use a system call to run Xfoil. It then loads the results into a data structure which you can then use in your Matlab script.For example to deflect the trailing edge of a NACA0009 by 5deg at 65% chord and run multiple incidence angles...[pol foil] =...

For a symbolic input function f, returns the symbolic Hessian matrix. A real time saver imho I don't know how useful anyone will find this, but eh, my professor made us do it on the test, so I figure this will save at least someone the headache of having to find the Hessian by hand (provided they...

this function calculates the price of Call option based on the GARCH option pricing formula of Heston and Nandi(2000). The input to the function are: current price of the underlying asset, strike price, unconditional variance of the underlying asset, time to maturity in days, and daily risk free...

write_matrix_bin(f,m) saves the matrix "m" in a binaryfile "f". write_matrix_bin is a lot faster than the built in function save(), andtakes up much less diskspace than the old "save -v6" which doesn't use compression.write_matrix_bin also includes an option for compression with...

Sometimes inside a decorator that creates a function with a generic (*args, **kwargs) signature, you want to access a value passed for a particular parameter name to a wrapped function, but don't know whether that value will be passed as a positional or keyword argument, or whether the wrapped...

Because of the "erfc" function, the processing time is very small.


Platforms: Matlab

This function makes it easier to use the timeit module from the interactive interpreter. You should just specify function with (optional) arguments to run, optional number of runs, and optional name of module (which if not specified defaults to the name of the function).

This script defines a decorator that allows for an abbreviated slice syntax in function arguments: {start:end}. Step is notsupported. Valid quickslices are dictionaries with a single integer key which has an integer value. Arguments can be strings or integers, and indicate the positional or...

Flexible enumerate() script adds an additional start argument to the built-in enumerate function.

This script shows how you can use intospection to create a function wraper that verify Eiffel like contracts.

This script allows that arbitrary number of commands to be strung together with each one feeding into the next ones input.

This script defines the whoaminow() function that can be used inside a function to determine, at the time it is called, the name under which that function has been invoked.


Platforms: Windows, Mac, *nix, Python, BSD Solaris

This is a decorator that lets you annotate function definitions with argument type requirements. These type requirements are automatically checked by the system at function invocation time. The decorator frees you from writing type-checking boilerplate code by hand.

This script memoizes, but clears cache when last function call returns.It is suitable for dynamic programming.
