MATLAB: How to change the properties of a DSP “Array Plot” block from the command line

Best Answer

Get a handle to the array plot configuration object then modify the desired properties. For example,

>> MyScopeConfiguration = get_param(gcbh,'ScopeConfiguration')
>> MyScopeConfiguration.YLimits = [-1 100];

See here for the full example and configurable properties:

MATLAB: How to specify overlap in dsp.SpectrumEstimator object

Overlap property does not exist in the 'dsp.SpectrumEstimator' object as of MATLAB R2017a. To implement the overlap option there are two options -

1. Use the 'dsp.AsyncBuffer' object to capture the overlapped frame and then step that through the object 'dsp.SpectrumEstimator'. This object was introduced in R2017a.

2. Using vector indexing, manually divide the input signal into frames including the overlapping samples. Then step these frames through the 'dsp.SpectrumEstimator', one at a time.

Please refer to the attached script which shows the use of 'dsp.AsyncBuffer' object to implement the overlap in 'dsp.SpectrumEstimator' and obtain the equivalent spectrum as obtained from 'pwelch'.

MATLAB: How to add multiple (i.e. more than 4) axes on a Simulink Scope

1. If you simply "drag" in the Simulink Layout editor, you will only be able to see a maximum 4x4 grid. If you "Click and drag" within the Layout of the scope, you will be able to expand.

(see the GIF under "Layout")

2. From command line:

>> myScopeConfiguration = get_param(gcbh,'ScopeConfiguration');
>> myScopeConfiguration.LayoutDimensions = [5 1]; % max is 16x16
