About the Author

Scientific Programming School
Scientific Programming School

Scientific programming is a rapidly growing multidisciplinary field that uses advanced computing capabilities to understand and solve complex problems. 

The Scientific programming school team helps you to learn the use of scientific programming languages, such as CUDA, Julia, OpenMP, MPI, C++, Matlab, Octave, Bash, Python Sed and AWK including RegEx in processing scientific and real-world data. The team is formed by PhD educated instructors in the areas of Computational Sciences.

The team deploys interactive courses at Scientific Programming School (now Learnitive.com) which is an interactive and advanced e-learning platform for learning scientific coding giving you the opportunity to run scientific codes/ OS commands as you learn with playgrounds and Interactive shells inside your browser.
