TABLE OF CONTENTS Recent releases of MATLAB have introduced many changes, which are documented in the Release Notes available from the Help Browser. The changes include new language features, new functions, and alterations to function names or syntax that require M-files to be rewritten for future compatibility. In this appendix we give a highly selective summary of changes introduced in versions 5.0 onwards of MATLAB. Our aim is to point out important changes that may be overlooked by users upgrading from earlier versions and that may cause M-files written for earlier versions to behave differently in MATLAB 6.
New, improved random number generators introduced. Previously, the state of the random number generators was set with
rand('seed',j), randn('seed',j) If this syntax is used now it causes the old generators to be used. The state should now be set with
rand('state',j), randn('state',j)Functions renamed as follows: fmin ? fminbnd, fmins ? fminsearch, nnls ? Isqnonneg.
Matrix computations based on LAPACK, rather than LINPACK as previously. MATLAB now takes advantage of Hermitian structure when computing the eigensystem of a complex Hermitian matrix, and of Hermitian definite structure when computing the eigensystem of a Hermitian definite generalized eigenvalue problem. Eigenvalues may be returned in a different order than with earlier versions of MATLAB, eigenvectors may be normalized differently, and the columns of unitary matrices may differ by scale factors of modulus unity.
As a result of the switch to...
