my example :

listProcessingUnitCallback={...
    'signalstatistics_callback','signalFFT_callback','inverseFFT_callback','harmonic_callback','PSD_callback',...
    'spectralCoherence_callback','angle_callback','orderSpectrum_callback','invorderSpectrum_callback',...
    'synchronousaverage_callback','synchronousaveragespectrum_callback','residual_callback','residualspectrum_callback',...
    'envelope_callback','envelopespectrum_callback','miscProcessing_callback','Spectrogram_callback',...
    'Cyclostatio_callback','FIRFilter_callback','TOPdetect_callback'};
handle.ProcessingConfig = uicontrol(...
            'Style' , 'checkbox' ,...
            'String' , 'Processing1' ,...
            'Tag' , 'processing1' ,...
            'Callback' ,listProcessingUnitCallback(1),...          how to write this ?
            'Units' , 'Normalized' ,...
            'Position' ,[0. 0.97 1 0.03],...
            'Parent' ,handle.actionsButtonsConfigProc);

Fabienne - I think that you may want to create an array of function handles rather than an array of (string) function names. For example,

listProcessingUnitCallback={...
    @signalstatistics_callback,@signalFFT_callback};

and then you would extract the callback as

'Callback' ,listProcessingUnitCallback{1},...

using the {} braces rather than the () brackets.

Fabienne's answer moved here

it's exactly what I want to do but with your syntax I have the same error message : Error while evaluating UIControl Callback.

Fabienne - please copy and paste the full error message to this question so that we can understand what is going on. It could be that the signature of your functions (in the cell array) do not match the expected signatures of the uicontrol callback.
