. The kronprod object allows this shortcut to be performed when possible.
. Provides efficiency and ease of computation power while dealing with large matrices.
- gradient function is now supported to compute gradient of a function or sampled data.
- histc computes histogram counts.
Plotting
- boxplot: Creates a box plot. Returns the statistics of the input data and the handles of the graphics object.

Altair Simulation -driven design changed product development forever, enabling engineers to reduce design iterations and prototype testing. Increasing scientific computing power expanded the opportunity to apply analysis, making large design studies possible within the timing constraints of a program. Now engineering adoption of AI is transforming product development again. The combination of physics-based simulation-driven design with machine learning, leveraging the latest in high-performance computing, enables teams to explore more and identify high-potential designs – while rejecting low-potential concepts – even earlier in development cycles.
Compose is an environment for doing math calculations, manipulating, and visualizing data, programming, and debugging scripts useful for repeated computations and process automation. Compose allows users to perform a wide variety of math operations including linear algebra and matrix manipulations, statistics, differential equations, signal processing, control systems, polynomial fitting, and optimization. The broad set of native CAE and test result readers accelerates system understanding and works with Altair Activate to support model-based development, for multi-domain and system of systems simulations. Altair Embed completes the model-based design portfolio with automated code generation, allowing for the testing and verification of embedded systems.
Altair Compose: Introduction to Signal Processing
Using Compose for Signal Processing allows useful information to be extracted from sensors that cannot be measured, can improve transmission, storage efficiency, and quality of signal. It will help you have a more clear understanding of phenomena in many applications. The "Signal Processing" playlist has been organized in 13 modules covering amongst others fundamentals, file i/o, frequency domain as well as time domain analysis.
