The Matrix Computation Toolbox contains a MATLAB function signm that computes the matrix sign function. It computes a Schur decomposition then obtains the sign of the triangular Schur factor by a finite recurre
Indexing into a matrix is a means of selecting or modifying a subset of elements from the matrix. MATLAB®has several indexing styles that are not only powerful and flexible, but also readable and expressive. Matrices are a core component of MATLAB for organizing and analyzing data, and index...

Calling svd for numeric matrices that are not symbolic objects invokes the MATLAB® svd function. Matrix computations involving many symbolic variables can be slow. To increase the computational speed, reduce the number of symbolic variables by substituting the given values for some variables. ...
This MATLAB function solves the symbolic system of linear equations in matrix form, X*A = B for X.
syms f(x) [1 2]creates the symbolic arrayf(x) = [f1(x) f2(x)], the symbolic functionsf1andf2, and the symbolic scalar variablexin the MATLAB workspace. For multidimensional arrays, these elements have the prefixffollowed by the element’s index using_as a delimiter, such asf1_3_2....
