% |convert binary string to decimal
% |usage: dec = bin2dec( binary, M )
% |M is the decimal point placement
function dec = bin2decimal( binary, M )
dec = 0;
for i=1:length(binary)
dec = dec + binary(i).*2^(M-i);
end
I tried using this code. But im getting an error.
Undefined function or method 'bin2decimal' for input arguments of type
'double'.

Can you show the line where you called that function? Did you pass in a double instead of a string for the first argument?
Why does the comment say this: "usage: dec = bin2dec( binary, M )" when the function is called bin2decimal?
Is your bin2decimal function in your calling function's m-file, or is it in its own m-file? If it's in its own m-file, is that file on the path so that it can be found when you try to call it?

variant
bstr - binary string
function dec = bin2decimal(bstr,M)
% bstr = string array!!!
M = 6;
k = bstr - '0';
dec = k*2.^((numel(k):-1:1)-M).';
eg
bstr = '01001001110';
dec = bin2decimal(bstr,6)
IN your function
function dec = bin2decimal( binary, M )
% binary - string array, eg: '0100110001110'
dec = 0;
for i=1:length(binary)
dec = dec + (binary(i) - '0').*2^(M-i);
end
