Do you need to make a fast Fourier transform or to solve a differential equation system? Do you perform a complex data analysis trying to gather all methods in one place as a source code? Then library of numerical methods is for you!
ALGLIB is currently one of the best libraries of the multi-language algorithms. Below are ALGLIB features mentioned on the official website:
CAlglib class static functions should be used to work with the library - all library functions are moved to CAlglib system class as static functions.
testclasses.mq4 and testinterfaces.mq5 test cases scripts are attached together with a simple usealglib.mq4 demo script. Include files of the same name (testclasses.mqh and testinterfaces.mqh) are used to launch test cases. They must be placed to \MQL4\Scripts\Alglib\Testcases\.
Note:
testclasses.mq4 script execution takes quite a long time (about 30 minutes).
