PLOT3D was created by NASA Ames Research Center in 1982 by Pieter Buning [1] and remains an often used file format. It can only store a structured grid. The structured grid allows random access, that is by knowing the block number, i location, j location, and k location, any grid point value
A MEX file is a type of computer file that provides an interface between MATLAB or Octave and functions written in C, C++ or Fortran.It stands for "MATLAB executable". When compiled, MEX files are dynamically loaded and allow external functions to be invoked from within MATLAB or Octave as if they were built-in functions.
In computer science, a lookup table (LUT) is an array that replaces runtime computation with a simpler array indexing operation, in a process termed as direct addressing.The savings in processing time can be significant, because retrieving a value from memory is often faster than carrying out an "expensive" computation or input/output operation. [1]
When creating a MATLAB function, the name of the file should match the name of the first function in the file. Valid function names begin with an alphabetic character, and can contain letters, numbers, or underscores. Variables and functions are case sensitive. [44]
MATLAB Central currently houses around than 145,000 questions in its MATLAB Answers database. [24] The company actively supports numerous academic institutions to advance STEM education (primarily through the use of MathWorks products), including giving funding to MIT Open Courseware and MITx.
Octave programs consist of a list of function calls or a script. The syntax is matrix-based and provides various functions for matrix operations. It supports various data structures and allows object-oriented programming. [25] Its syntax is very similar to MATLAB, and careful programming of a script will allow it to run on both Octave and ...
It is based on quasi-linearization, which is the approximation of the non-linear system under investigation by a linear time-invariant (LTI) transfer function that depends on the amplitude of the input waveform. By definition, a transfer function of a true LTI system cannot depend on the amplitude of the input function because an LTI system is ...
A large number of algorithms for classification can be phrased in terms of a linear function that assigns a score to each possible category k by combining the feature vector of an instance with a vector of weights, using a dot product. The predicted category is the one with the highest score.
