Now many programmers are using GCC to better apply GCC. Currently, GCC can be used to compile programs in C/C ++, FORTRAN, JAVA, OBJC, ADA, and other languages. You can select the language to install. This article describes how to install GCC in Linux by taking GCC4.9.2 installation in RedHatLinux as an example (the latest GCC version is not used because it is required during project development. Before installation, you must have a cc, gcc, and other
Recently, work has been transformed into a data development area to build a data development environment locally. I have three years of Python development experience, immediately think of using NumPy, scipy, Sklearn, pandas set up a data development environment.

After trying to write a program to solve the problem, I began to find a variety of libraries on the Internet to solve the feature values and feature vectors, especially the feature values of large-scale sparse matrices, the problem of generalized feature values is not considered because the generalized feature values can be easily converted into general feature values. On the internet I found a good article to tell the author looking for a variety of libraries, which saves me a lot of time: http

For example, if you want to insert c code or FORTRAN or Ada code in c ++ code, you can use extern, for example, you want to use the exit function in c format, and add extern "C" in front of it. now,
extern "C" void exit(int);
However, note that the C ++ compiler only supports C syntax and other FORTRAN syntax. The Ada Syntax is not necessarily supported, or is not fully supported
Shtools is an open-source library written in FORTRAN that is specifically used to process ball harmonic functions. For more information, see here, all of them are described in detail on the official website. Although they are very detailed, they are still difficult to compile. Next I will record the compilation steps under Ubuntu.
First, shtools depends on three libraries: fftw, Blas, and LAPACK. The fftw library is a database of Fourier transformatio

programs on sles8, applications running Java threads will benefit from NPTL's RHEL3 implementation.
The advantage of the open source code model is its flexibility, and the POWER version of Linux is also flexible. That is to say, developers can find general references for development on RHEL3 and SLES8. Compilers, IBM Java Developer's Kit, and development tools such as the Popular integrated development environment Eclipse are examples of free and available tools in these two Release versions.

Mix C and matlab in Linux and mix linuxmatlab1 Overview 1.1 Introduction to Matlab
MATLAB is a commercial mathematical software developed by MathWorks. It is used for algorithm development, data visualization, data analysis, and numerical computing. It is a high-level computing language and interactive environment. It consists of two parts: MATLAB and Simulink. MATLAB is widely used!
MATLAB can also be mixed with other advanced languages such as C/C ++/C #/Java/
stress analysis of hot rolling and Cold Roll, this hardware facility is usually not used for simulation.
A high-level mathematical model can be created to generate the desired data and graphics.
The figure above shows you:
Note the last sentence: integrate with C ++ Fortran COM and Java; Integrate C, C ++, Fortran, COM, and Java.
In fact, there are many functions in MATLAB, such as LS, Dir, mkdi

Scons Introduction
Scons is an openSource code, The next generation of program building tools written in Python. Its initial name was sccons, developed based on the cons software written in Perl, which won the SC build competition held by software carpentry in August 2000. Now sccons has been renamed as scons, so that it is no longer associated with software carpentry. Of course, there is anot
uncertainty on performance or the memory overhead of the dynamic compiler itself.
Therefore, although JIT compilation technology can provide a performance level equivalent to (or even better) the static language performance, dynamic compilation is not suitable for some applications. In these cases, ahead-of-time (AOT) Compilation of Java code may be a suitable solution.
AOT Java Compilation
Generally speaking, local compilation in Java should be a simple application of the compilation technolog

With the previous introduction to the Parallel Computing preparation section, we know that MPI (Message-passing-interface messaging interface) implements parallelism as a process-level message passing through the process through communication. MPI is not a new development language, it is a library of functions that defines what can be called by C, C + +, and FORTRAN programs. These libraries are primarily concerned with functions that communicate betw
