The Matbasic program for Windows platform is designed and purposed for solving difficult mathematical problems with the option of text and graphical output of results. The Matbasic is an integrated development environment of mathematical solutions. The program is based on a specially developed high-level programming language translator and the language is the most appropriate for solving mathematical and technical problems. The Matbasic language combines the simplicity of the BASIC syntax and the flexibility of such high-level languages as C and Pascal. The set of commands and operators the language has is wide enough for the development of algorithms of any level of complexity. The program allows to conduct any operations with real-valued and complex numbers also as with matrices. It has a wide range of built-in linear algebra functions, solutions of non-linear equation systems, numerical integration and plenty of other functions. This software allows to create and store a personal library of functions. An Matbasic calculation tool has a full-functional debugger which allows to trace current program state at any step of its run.

Matbasic is provide following calculation tools:

• Base programming and calculation tools;
• Full complex arithmetic's;
• Linear algebra and operations. Solving systems of linear equations, eigenvalue problems, and singular value problems. Matrix factorizations (LU, Cholesky, QR, SVD, Schur);
• Polynomial problems. Roots of the polynomial. Polynomials multiplication, division and other functions;
• Numerically evaluate integral of function;
• Solve non-linear system of equations;
• Find zero of a function of one variable (solve non-linear equation);
• Minimize a function of one and more variables;
• Solve initial value problems for ordinary differential equations (stiff and non-stiff);
• and others;
