Dear Community,

I need to implement the next equation in Matlab:

ENOB = log2 (((2^B)*((2^L+1)^(1/2))*R^(L+0.5))/pi^L)

And from the input variables B, ENOB and R, extract the Output L. Any idea about how to make it?

Thanks in advance,

syms L
ENOB=input('ENOB ');
R=input('R ');
B=input('B ');
solve(ENOB - (log2 (((2^B)*((2^L+1)^(1/2))*R^(L+0.5))/pi^L)))

You can do this-

L=solve(ENOB - (log2 (((2^B)*((2^L+1)^(1/2))*R^(L+0.5))/pi^L)))

this will assign the value to variable L, it won't be empty anymore.
