Every matrix is named after its number of rows and columns; for example, a 2x3 matrix is a matrix with two rows and three columns. In matrix math, all matrices are written as the number of rows x the number of columns. This row x column value is called the order of the matrix. ...
This table shows the performance gain of using the Matrix Library, compared to Microsoft*‘s D3DXMATRIX class from D3DXMath.H of DirectX*7, which implements the same functions the scalar way. Please note that this is a synthetic test, so those ratios may change when measured in application. ...

Indeed, the above formula is telling you that in order to find the inverse you need to compute the determinant of the matrix, and also you need to compute the adjoint matrix. Unlike what appearances may suggest, this could be very labor intensive with the size of the matrix is large (...

Notably, Shuster’s definition is employed by NASA’s Jet Propulsion Laboratory and, in computer graphics, within the Microsoft DirectX Math Library. The differences between Hamilton’s and Shuster’s quaternion definitions are summarized in the following table: Hamilton’s Definition Shuster’s ...
A matrix can be tested to see if it is symmetric in the Wolfram Language using SymmetricMatrixQ[m]. Written explicitly, the elements of a symmetric matrix have the form (4) The symmetric part of any matrix may be obtained from (5) A matrix is symmetric if it can be expressed ...
To evaluate a matrix math expression, just create aParser<Derived>instance and pass the equation string to itseval()method, which will return the result of the evaluation as aValue<Derived>object. The template parameterDeriveddenotes the matrix data type used for each value in the expression, ...
To show all the functions in Symbolic Math Toolbox™ that accept symbolic matrix variables and symbolic matrix functions as input, use the commandmethods symmatrixandmethods symfunmatrix. Tips You can create multiple symbolic objects in one call. For example,syms f(x) g(t) ycreates two symb...
