Publisher review:MATLAB provides an interactive development environment that has its own language. The application includes a high-level language that allows the execution of tasks that require high computing power. MATLAB facilitates implementation and makes it faster than with traditional programming languages such as C, C + + or Fortran.
The software can be used for oriented signal processing applications and images, in communications, control systems design, test and measurement, financial modeling and analysis, as well as bioinformatics.
MATLAB provides support mathematical functions for linear algebra, statistics, Fourier analysis, filtering. Finally, it includes 2D/3D graphics functions for visualizing data and allows the integration of MATLAB algorithms in (C + + / C, Fortran, Java, COM, and Microsoft Excel) and external languages.
Requirements:
- All Intel-based Macs with an Intel Core 2 or later
- RAM: 1024 MB (At least 2048 MB recommended)
- Disk space: 1 GB for MATLAB only
- TCP/IP is required on all platforms when using a license server.
Operating system:
Mac OS X 10.6.4 or later
