See if the Signal Processing Toolbox mag2db function will do what you want.
Note that it is necessary to use the absolute value of the argument:
xdB = mag2db(abs(x));
.

I want to get samples that contain decibels higher than 80 from this equation. Mag2db) Values are very low and negative Is there an add-on to get noisy samples over 80 db?

CConsider that:
dB80 = db2mag(80)
produces:
dB80 =
10.0000e+003
so multiplying them by 1E+4 or dibviding them by 1E-4 would do what you want.
