Version 6.7 (R2007a) Signal Processing Toolbox™ Software Release Notes

Version 6.7 (R2007a) Signal Processing Toolbox Software

This table summarizes what's new in Version 6.7 (R2007a):

New features and changes introduced in this version are

• lsf2poly and latcfilt Multi-Channel Input Support Added

• Circular Convolution (cconv) Function Added

• Spectrum Objects Partial Frequency Range Input Support Added

• cceps Factorize Algorithm Information Clarified

• dfilt.statespace Now Supports realizemdl Method

• ellip and ellipap Functions Enhanced

lsf2poly and latcfilt Multi-Channel Input Support Added

lsf2poly and latcfilt now support N-D array input where each column represents a separate input channel.

Circular Convolution (cconv) Function Added

A new function (cconv) that computes circular convolution has been added to the toolbox.

Spectrum Objects Partial Frequency Range Input Support Added

spectrum objects now support computing the spectrum and pseudospectrum on a user-specified vector of frequencies. This vector identifies the frequencies at which the spectrum or pseudospectrum is calculated.

cceps Factorize Algorithm Information Clarified

A more detailed explanation of the factorize algorithm and an example have been added to the cceps reference page.

dfilt.statespace Now Supports realizemdl Method

You can now create a Simulink block from dfilt.statespace objects with the dfilt realizemdl method.

ellip and ellipap Functions Enhanced

Both ellip and ellipap have been enhanced so that they are able to handle filters with more stringent requirements.
