Removing sub matrix from 3d matrix, if any values in the matrix exceed a certain min/max value

I am currently trying to do artifact rejection on my EEG.data. I have three sets of epoched data (in 3D matrices, for example 64(channels)x250(samplingtimes)x98(trials)).

I need to create a loop that runs through my EEG.data files and removes the trials containing values over/under 100 uV. For example, eye blink artifacts are easily detected in the Fp1 and Fp2 channels, which correspond to row 1 and 2 of the first dimension of my matrix. So if EEG.data(1:2, : , trial) >= 100, delete the trial. I am very new to matlab and would really appreciate any help.

for a=size(epochs_CG,3) % for the size of my 
    if epochs_CG(1:2, :, a)> 100
        epochs_CG(:,:,a) = [];
    elseif epochs_CG (1:2, :, a)< 100
        epochs_CG(:,:,a) = [];
    end
end

This did not work :P

discard=any( any(  epochs_CG(1:2, :, :)>=100  ,2) ,1);

epochs_CG(:,:,discard)=[];
