MathWorks MATLAB R2024a v24.1.0.2537033 with Documentation (x64)

With nearly 6,000 low-Earth orbit satellites (LEOs) in orbit currently and billions in private-sector funding flowing into space-related companies, interest in satellite communications is at an all-time high. The Satellite Communications Toolbox update in R2024a enables Satcom engineers to model scenarios and provides standards-based tools for designing, simulating, and verifying satellite communications systems and links. In addition, engineers can use the toolbox to design physical layer algorithms together with RF components and ground station receivers, generate test waveforms, and perform golden reference design verification.

R2024a also includes major updates to popular MATLAB and Simulink tools, including:

-Computer Vision Toolboxprovides algorithms, functions, and apps for designing and testing computer vision, 3D vision, and video processing systems. The product includes the ability to design algorithms, label data, and generate code for 2D and 3D vision tasks.
-Deep Learning Toolboxprovides a framework for designing and implementing deep neural networks with algorithms, pre-trained models, and apps. The toolbox enables support for architectures, such as transformers, and importing and co-simulating PyTorch and TensorFlow models.
-Instrument Control Toolboxconnects MATLAB directly to instruments such as oscilloscopes, function generators, signal analyzers, power supplies, and analytical instruments. The Instrument Explorer app can be used to manage devices with IVI and VXI Plug&Play drivers without writing code.
