No. Sorry, but no. You cannot use functions from one release in another release. They essentially check for this.Could you write codes with those names, adding them to your own toolboxes? Well, yes. But then you would need to write the code yourself.Having said that, I know that unwrap has certainly been around for ages. A quick check tells me it was introduced before 2006a. So at least 16 years ago, and I recall it before then.As far as wrap goes, it does not exist in MATLAB R2020b, then I checked R2021a. Not in there either. I guess this means it is time to install a new release for me. Ok. Checked. wrap does also not exist in R2021b, update 2, either. So unless you have this toolbox:which wrap -all/MATLAB/toolbox/matlab/testframework/unittest/core/+matlab/+unittest/+internal/+diagnostics/FormattableString.m % matlab.unittest.internal.diagnostics.FormattableString method/MATLAB/toolbox/matlab/testframework/unittest/core/+matlab/+unittest/+internal/+diagnostics/LeafFormattableString.m % Shadowed matlab.unittest.internal.diagnostics.PlainString methodthen you will not have wrap. Are you a wrapper? Is it my birthday already? ;-)

Direct link to this answer ⋮ Direct link to this answer Hi,While there is no "zpk" function in the Signal Processing Toolbox, there is a method called "zpk" of the object "digitalFilter". If you have the Signal Processing Toolbox, you can call the "zpk" function if the input is a digitalFilter object. Here's an example:hpFilt = designfilt('highpassiir','FilterOrder',8, ... 'PassbandFrequency',75e3,'PassbandRipple',0.2, ... 'SampleRate',200e3);[z,p,k] = zpk(hpFilt);You can learn more about it here: See Also Categories Community Treasure Hunt Find the treasures in MATLAB Central and discover how the community can help you!

Same class. To determine the class, use the class function. If you do not specify the target for the subtitle, then the subtitle function adds the subtitle to the graphics object returned by the gca command. Name-Value ArgumentsSpecify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter. Before R2021a, use commas to separate each name and value, and enclose Name in quotes. Example: subtitle('My Subtitle','FontSize',12) specifies a 12-point font size.NoteThe properties listed here are only a subset. For a complete list, see Text Properties.FontSize — Font size 11 (default) | scalar value greater than 0Font size, specified as a scalar value greater than 0 in point units. One point equals 1/72 inch. To change the font units, use the FontUnits property.If you add a title or subtitle to an axes object, then the font size property for the axes also affects the font size for the title and subtitle. The title and subtitle font sizes are the axes font size multiplied by a scale factor. The FontSize property of the axes contains the axes font size. The TitleFontSizeMultiplier property of the axes contains the scale factor. By default, the axes font size is 10 points and the scale factor is 1.1, so the title and subtitle each have a font size of 11 points.Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64FontWeight — Thickness of text characters 'normal' (default) | 'bold' Thickness of the text characters, specified as one of these values: 'normal' — Normal weight as defined by the particular font'bold' — Thicker characters outlines than normal MATLAB® uses the FontWeight property to select a font from those available on your system. Not all fonts have a bold font weight. Therefore, specifying a bold font weight could still result in the normal font weight. The SubtitleFontWeight property for the associated axes affects the FontWeight value for the subtitle. TipsBy default, the Interactions property contains editInteraction so the text can be edited by clicking on the text. To disable this interaction, set the Interactions property of the text object to [].Version HistoryIntroduced in R2020b

M.N is the number of channels such that N = size(audioIn,2). Trailing singleton dimensions are removed from the output S. Data Types: single | doubleF — Center frequencies of mel bandpass filters (Hz) row vector Center frequencies of mel bandpass filters in Hz, returned as a row vector with length size(S,1). Data Types: single | doubleT — Location of each window of audio (s) row vector Location of each analysis window of audio in seconds, returned as a row vector length size(S,2). The location corresponds to the center of each window. Data Types: single | doubleAlgorithmscollapse allThe melSpectrogram function follows the general algorithm to compute a mel spectrogram as described in [1].In this algorithm, the audio input is first buffered into frames of numel(Window) number of samples. The frames are overlapped by OverlapLength number of samples. The specified Window is applied to each frame, and then the frame is converted to frequency-domain representation with FFTLength number of points. The frequency-domain representation can be either magnitude or power, specified by SpectrumType. If WindowNormalization is set to true, the spectrum is normalized by the window. Each frame of the frequency-domain representation passes through a mel filter bank. The spectral values output from the mel filter bank are summed, and then the channels are concatenated so that each frame is transformed to a NumBands-element column vector.Filter Bank DesignThe mel filter bank is designed as half-overlapped triangular filters equally spaced on the mel scale. NumBands controls the number of mel bandpass filters. FrequencyRange controls the band edges of the first and last filters in the mel filter bank. FilterBankNormalization specifies the type of normalization applied to the individual bands.The mel scale can be in the O'Shaughnessy style, which follows [2], or the Slaney style, which follows [3].References[1] Rabiner, Lawrence R., and Ronald W.
