The following scripts compute the eigenvalues both symbolically and numerically. In each case the parameter p is varied from 0 to 2 in steps of 0.1. However, only the eigenvalues which correspond to p=0.9 and 1.9 are displayed. The script e4sX02.m determines the eigenvalues symbolically, and...

Symbolic Math Toolbox provides tools to solve, plot, and manipulate mathematical expressions, both analytically and numerically with high precision. From the results of symbolic computations, you can also generate MATLAB®functions, Simulink®Function blocks, and Simscape™ equations to use with oth...
The condition number ranges from 1 for a numerically stable matrix to Inf for a singular matrix. c = cond(A) c = 61.9839 It is seldom necessary to form the explicit inverse of a matrix. A frequent misuse of inv arises when solving the system of linear equations Ax = b. The best way...
Thecatfunction is useful for assembling a collection of matrices into a multidimensional array, and thezerosfunction is useful for preallocating a multidimensional array. Tips Results obtained usingpageinvare numerically equivalent to computing the inverses of each of the same matrices in afor-loop. ...
