The installation of JShellLab is very simple:
-
Step 1 Download and unzip the .zip download.
-
Step 2 Run the proper script for your platform, i.e. the .sh scripts for Unix like systems and the .bat scripts for Windows.
The JShellLab.zip download contains both the sources and all the relevant libraries to build JShellLab with ant.
To build JShellLab with Netbeans, simply specify the corresponding project to Netbeans.
Building with Gradle and support for fat jar that supports the DeepLearning4j library and Apache Spark
To build JShellLab with Gradle, unzip the zipped file, go to the root folder where the contents are unzipped and type:
-
gradle clean
-
gradle jar
The executable should be placed in the build/libs folder
You can also build a fat jar, the JShellLab-all.jar, that supports the DeepLearning4j effective Java library for Deep Learning (it provides very fast native numerical processing operations). Also, it supports Apache Spark for Big Data Processing. The Gradle command is:
- gradle fatjar
a fat jar is produced with all the DeepLearning4j and Apache Spark functionality!
Therefore we can run Deep Learning and Apache Spark algorithms in scripting mode, with either Groovy or the JShell of Java 9+.
Note that F7 executes the selected script code with the JShell.
The JShellLab environment aims to provide a MATLAB/Scilab like scientific computing platform that is supported by a scripting engine implemented in Groovy language. The JShellLab user can work either with a MATLAB-like command console, or with a flexible editor based on the rsyntaxarea component, that offers more convenient code development. JShellLab supports extensive plotting facilities and can exploit effectively a lot of powerful Java scientific libraries, as JLAPACK , Apache Common Maths , EJML , MTJ , NUMAL translation to Java , Numerical Recipes Java translation , Colt etc.
JShellLab scripts can be easily combined with MATLAB, thus the scientist can combine the flexibility of Groovy with the computational effectiveness of MATLAB.
