For example, the following are supported:</p> <ul> <li><p><b>a = lpsd(b1,b2,b3)</b></p></li> <li><p><b>[a1,a2,a3] = lpsd(b1,b2,b3)</b></p></li> </ul> </li> <li> <p>Model fitting tools:</p> <ul> <li><p><b>curvefit</b> for doing non-linear least-squares, now including weights</p></li> <li><p><b>lscov</b> for doing linear least-squares fitting</p></li> <li><p><b>straightLineFit</b> is a wrapper of <b>lscov</b> for fitting data with a straight-line</p></li> </ul> </li> <li><p>Operators, +-.*./*/, all conform to more standard MATLAB type behaviour. For example, adding a single AO to a vector of AOs results in a vector of AOs where the single AO is added to each element of the vector.</p></li> <li><p>Digital filtering with IIR filters now has two possible ways of applying a bank of filters. By specifying the ‘<b>bank</b>’ parameter, the filters will be applied as a ‘<b>serial</b>’ bank or a ‘<b>parallel</b>’ bank.</p></li> <li><p>Two new noise-generators are included, <b>noisegen1D</b> and <b>noisegen2D</b> (which can produce correlated data streams).</p></li> <li><p>AOs can now be built from a set of built-in models. Users can also write their own models and point LTPDA to a directory (or more than one) containing those model files.</p></li> <li><p>The user preferences of LTPDA are now controlled via a graphical user interface. To adjust the user preferences, run <b>LTPDAprefs</b>.</p></li> <li><p>Two new transfer function representations are present as user classes of this version of the toolbox. The class <b>parfrac</b> allows the user to build transfer function models that are a series of partial fractions; the class <b>rational</b> allows the user to build a transfer function as a rational polynomial in s. Some converters also exist to go between these and the existing transfer function models, <b>pzmodel</b> (pole/zero models), <b>miir</b> (IIR filters) and <b>ssm</b> (state-space models).</p></li> <li><p>A new method, <b>ao/heterodyne</b>, to heterodyne data at a given frequency.</p></li> <li><p>All transfer function representations and digital filters now can be assigned input and output units. This means that units are now propagated through fully through any analysis.</p></li> <li><p>A new <b>rebuild</b> method to rebuild objects from their self-contained history trees.</p></li> <li> <p>New graphical user interfaces</p> <ul> <li><p>modelViewer - a viewer for the built-in ao and ssm models</p></li> <li><p>constructor - a helper for writing object constructors (rewritten)</p></li> </ul> </li> <li><p>New convenient AO methods to apply gain and to add an offset to data (<b>scale, offset</b>).</p></li> <li><p>Transfer function estimators now return error terms in the <b>procinfo</b> field of the result <b>ao</b>.</p></li> <li><p>Units are not automatically simplified. Instead the user can now do that on demand with the <b>simplifyYunits</b> method. There are also methods to convert between Hz and s: <b>HzToS</b> and <b>sToHz</b>.</p></li> <li><p>Digital IIR filters are now initialised to a state based on the input data. This should reduce start-up transients.</p></li> <li><p>Data in AOs can be converted from one type to another using the new <b>ao/convert</b> method.</p></li> <li><p>Pole/zero models (<b>pzmodel</b>) now support a delay parameter.</p></li> </ul> <!-- END: Content file --> </p> <br> <br> <table class="nav" summary="Navigation aid" border="0" width= "100%" cellpadding="0" cellspacing="0"> <tr valign="top"> <td align="left" width="20"><a href="releasenotesV2_0_1.html"><img src= "b_prev.gif" border="0" align="bottom" alt= "Version 2.0.1 LTPDA Toolbox Software"></a> </td> <td align="left">Version 2.0.1 LTPDA Toolbox Software</td> <td> </td> <td align="right">LTPDA Toolbox</td> <td align="right" width="20"><a href= "ltpda_top.html"><img src="b_next.gif" border="0" align= "bottom" alt="LTPDA Toolbox"></a></td> </tr> </table><br> <p class="copy">©LTP Team</p> </body> </html>
