• Although C# applications are intended to be economical with regards to memory and processingpower requirements, the language was not intended to complete directly on performanceand size with C or assembly language.Therefore, we decided to use Microsoft Visual C# to build the new neural network software tool.5
The neural network software toolAfter choosing the programming language we started by constructing a library with the basic mathematicalsupport for a neural network. At the same time, we explored C# language as well as MicrosoftVisual C# Express Edition features. During the study of C#, we constructed some graphical controlsthat were included in the first version of the software tool.In September, appeared a very useful neural network library written in C#, so we investigated thislibrary. With a solid knowledge of the code we have rewritten and integrated these functionalities inthe fist version.First versionThe first version of the written software included a set of basic routines with the purpose of aiding theconstruction of neural networks algorithms. These routines were grouped into a library and consistof the following functions:1. Matrix arithmetics (addition, subtraction, product);2. Matrix partitioning;3. Matrix sorting of rows or columns;4. Transpose matrix;5. Elementary operations on rows or columns of matrices (finding the minimum/maximum elementand the position of it, adding or deleting rows, altered some rows elements );6. Matrix normalization;7. Vector dot product;8. Initializing matrices.6
