Sequence expressions, asynchronous computations and queries are particular kinds of computation expressions. The Chinese also used the armillary sphere in aiding calendrical computations and calculations. Nearly all scientific computations involve linear algebra. FIR algorithms allows for a zero input-output latency that is useful for real-time convolution computations. APL is a language for mathematical computations. Historically, matrix multiplication has been introduced for making easier and clarifying computations in linear algebra. The "integrator" is the core rendering algorithm used for lighting computations. GPUs are optimized for parallel pixel computations. They argued that neural computations explain cognition. Version 1.2 allowed implementations to bring extra precision in intermediate computations for platforms like x87. The Lifting scheme is an optimization where these two computations are interleaved. Euler spirals have applications to diffraction computations. Wolfram Mathematica includes collections of curated data provided for use in computations. Examples of symbolic computations are given below. Furthermore, even single neurons appear to be complex and capable of performing computations.
