failed binary to decimal

hello everyone, I have the code below , which I want to use for conversion of binary to decimal, but each time I run the program, the software keeps saying >> binary_conversion

Not enough input arguments.

Error in binary_conversion (line 2)

count=numberofdigits(x);

Please I need held on this.

Here is the code:

function decimal_value= binary_conversion(x)
count=numberofdigits(x);
pow=0;
decimal_value=0;

for i=1:1:count
    n=mod(x,10);
    decimal_value=decimal_value+(n*2^pow);
    pow=pow+1;
    x=floor(x/10);
end

end

How do you try to run the code? Using the green triangle in the editor? Then now input argument is used.

Call it from the command line or from another script or function with an input:

d = binary_conversion(10010101)

A simplification of your code:

function d = binary_conversion(x)
count = numberofdigits(x);
mult  = 1;
d     = 0;
for i = 1:count
    d = d + mod(x, 10) * mult;
    mult = mult * 2;
    x = floor(x / 10);
end
end
