jMatLab

jMatLab is a free platform for mathematical and numerical computations which is a clone of Matlab and Octave and runs on any platform where Java is installed or on the Web browser. jMatLab provides features such as Arithmetic, Variables, String Manipulations, Commands and Operators, Functions, Polynomials, Vectors, Differentiation, Equations (Differential), Equations (Linear Systems), Equations (Nonlinear), Equations (Nonlinear Systems), Indefinite Integrals, Input and Output, Matrices, Numerical Integration, Plots, Programming, Statistics (Data Fitting), Statistics (Descriptive), Statistics (Histograms), Statistics (Random Numbers), Taylorpolynomial and Transformations.

jMathLab has its own help system where all programming modules are arranged in groups and users can list all functions which come with the program. jMatLab includes several other projects licensed by GNU such as Jasymca, JMathLib, Lapack, epsgraphics, Blas and R-text textarea and to compile them, users will need third-party jar libraries such as jwork-jhplot-light.jar, epsgraphics.jar, lapack_simple.jar, lapacke.jar, f2jutil.jar, and blas.jar.

JMathLab’s Commands and Operators include format, syms, clear, who, path and Operators where only one command per text input is allowed. There are more than 250 built-in functions included with jMathLab. They are implemented as an external MatLab functions (with the extension .m) or as a Java classes where users can look at them using the command path.

jMathLab is well suited for statistical calculations where users can calculate the major statistical characteristics for matrices and vectors. jMathlab supports custom tailored numerical integration of certain probability distributions. jMathlab supports string manipulation on a basic level where one can add two strings together, find an index of a substring and extract a substring.
