Hi all,
I'm working on a model using piezodevice physics in the frequency domain, and I'm trying to plot admittance in dB (rather than siemen). I've found the admittance by taking the surface integral of the current density (pzd.JZ) over one of the electrodes, which results in a table with admittance values for each frequency. Is there any way to apply additional mathematical manipulation to the values in that table? To convert to dB, I need to take 10*log10(x) for each admittance value. I've tried doing the 10*log10(abs(pzd.JZ)) as the expression in the surface integral, but that doesn't work... though admittedly my math is a little fuzzy as to why not.
It seems like there must be an easy way to manipulate data in a table, but I can't seem to find it. Any advice would be greatly appreciated!
Thanks,
Jillian
