I exported a diagram from FDTD simulation, and now I want to change the magnitude to dB, here is the exported codes:
ax1 = axes; plot(lum.x0,lum.y0) set(ax1, 'XLim', [1.49806e-06 1.60194e-06]) set(ax1, 'YLim', [-0.0232806 1.22328]) set(ax1,'XGrid', 'on') set(ax1,'YGrid', 'on')
I just wondering how to convert the magnitude to dB? I know there is a function called mag2dB, but i just dont know how to use it. any help would be very appreciate.
