how to use matlab to convert some value into dB and vise versa

if A = 10*log10(K)for example how to perform the following on MATLAB K = inverse log(A/10)

Answer 1

[Mischa Kim]

Amina, use

 K = 10^(A/10)

Answer 2

[Sunil Kumar Yadav]

Amina use --->log10 command

Common (base 10) logarithm

so your expression become

A = 10*log10(K)

[Sunil Kumar Yadav]

use "log" for natural log and "log10" for log to the base 10 .Taking antilog of natural log use "exp(value)" and for antilog of base to 10 use 10.^value

log(2)

ans = 0.6931

exp(ans)

ans = 2

log10(pi)

ans = 0.4971

10.^ans

ans = 3.1416
