-

enter image description here

hi guys, want show 2-d array in matlab picture below,but dont know should search for. appreciated.

you looking spectogram plotting, surf map:

figure surf(y0, 'edgecolor', 'none'); view(0,90); axis tight;

where y0 matrix (assuming value in matrix magnitude).

you may use spectrogram plotting tool, check out spectrogram

i might add, in cases, use log(abs(y0)), log magnitude particularly @ showing results overall data not sparse.
