Enlarge Analyzing and visualizing data using the MATLAB desktop. The MATLAB environment also lets you write programs and develop algorithms and applications. Numeric Computation MATLAB provides a range of numerical computation methods for analyzing data, developing algorithms, and creating models. The MATLAB language includes mathematical functions that support common engineering and science operations. Core math functions use processor-optimized libraries to provide fast execution of vector and matrix calculations. Available methods include: Interpolation and regression Differentiation and integration Linear systems of equations Fourier analysis Eigenvalues and singular values Ordinary differential equations (ODEs) Sparse matrices MATLAB add-on products provide functions in specialized areas such as statistics, optimization, signal analysis, and machine learning. Refinement of gridded data using 2-D cubic interpolation. Enlarge Refinement of gridded data using 2-D cubic interpolation. Data Analysis and Visualization MATLAB provides tools to acquire, analyze, and visualize data, enabling you to gain insight into your data in a fraction of the time it would take using spreadsheets or traditional programming languages. You can also document and share your results through plots and reports or as published MATLAB code. Acquiring Data MATLAB lets you access data from files, other applications, databases, and external devices. You can read data from popular file formats such as Microsoft Excel; text or binary files; image, sound, and video files; and scientific files such as netCDF and HDF. File I/O functions let you work with data files in any format. Using MATLAB with add-on products, you can acquire data from hardware devices, such as your computer's serial port or sound card, as well as stream live, measured data directly into MATLAB for analysis and visualization. You can also communicate with instruments such as oscilloscopes, function generators, and signal analyzers.
