Try imresize() to make both matrices of equal length

dataAll_noHVbg_20200517 = imresize(dataAll_noHVbg_20200517, size(dataAll_noHVbg_20200516));

figure;
ax = axes();
hold(ax);
h1 = imagesc(dataAll_noHVbg_20200516, 'AlphaData', 0.5);
h2 = imagesc(dataAll_noHVbg_20200517, 'AlphaData', 0.5);
axis tight

This plot both matrices on the same axes using transparency.
