MATLAB: Conversion from binary to decimal

Question

Hello, I am trying to perform binary to decimal conversion somewhere in my code and I get the following error message. can someone please help.

item=bits(i,:));% item is a row gotten from the array named bits
scale=bin2dec('item');

??? Error using ==> bin2dec at 54 Binary string may consist only of characters 0 and 1

Error in ==> QUANTIZATION_BLOCK at 121 scale=bin2dec('item');

Thanks.

Answer 1

First of all, it would be

scale = bin2dec(item);  %no quotes!

Secondly, your bit values are probably values of 0 and 1, whereas bin2dec needs values of '0' and '1'

item = char('0' + bits(i,:));
