Hello, I'm trying to figure out how to write a function that will convert binary to decimal using recursion. BA is a 1 x n array of binary digits
function y = Bin2dec(BA)
n = length(BA);
if n == 1
y = BA;
else
y = Bin2dec(BA(n-1));
end
but I can't figure out the recursive part

Hi Rick,
You're aware of the MATLAB built in bin2dec function ain't u?
I've no idea if it's possible to call "Bin2dec" function from "Bin2dec" function?!!!
change the function name so that it won't interfere with matlab function
function y = _bin2dec(BA)
y = 0; BA = num2str(BA);
for n = 1:length(BA)
y = y + str2num(BA(n))^n-1;
end
end
hopefully that will do! ;)
Good Luck
