FVTool: filter array as parameter

I would like to pass a filter vector as a parameter to FVTool to automate different plots of my MATLAB script.

Example: I have this:

plotter = fvtool(getFilter(octaveFilterBank{1}), ...
    getFilter(octaveFilterBank{2}), ...
    'FrequencyScale', 'log', ...
    'Fs', Fs);

I want something like this:

% Init the array:
filter_array = [getFilter(octaveFilterBank{1}), ...
      getFilter(octaveFilterBank{2})];

% Plot:
plotter = fvtool(filter_array, ...
    'FrequencyScale', 'log', ...
    'Fs', Fs);

How can I do this?

Hi Nycholas,

Please give the following a try and let us know if it works for you:

filter1 = octaveFilter('CenterFrequency',1000);
filter2 = octaveFilter('CenterFrequency',2000);
filterArray = {getFilter(filter1), getFilter(filter2)};
fvtool(filterArray{:})

Thanks,

Gabriele.

Thank you Gabriele! You are right! Now it's working!

In my case, my final code is:

% Preallocate the filter bank:
octaveFilterBank = cell(1, 5);

for n = 1:5
    % Change the Center Frequency Dinamically:
    freq = 1000 * n;
    % Get the filter:
    filter = getFilter(octaveFilter('CenterFrequency', freq));
    % Add to filter array:
    octaveFilterBank{n} = filter;
end

% Plot filter array:
fvtool(octaveFilterBank{:})
