Convert base 2 to base 10 using loop

I've written this loop, but it produces a value of 128 for every number in the mult array instead of going from 128 to 64 to 32 etc. Can anyone tell me why? Thank you for your help!

%Convert base 2 numbers to base 10

base2 = [1 0 1 1 0 0 1];

mult = ones(1,length(base2))

for k = 1:length(base2)

    mult(1,k) = mult(1,k)*2^(length(base2-k))

   k = k+1

end

base10 = base2*mult'

There are two errors in your code

1) Bracket at wrong position (causes your problem to stay at 128 all the time)

mult(1,k) = mult(1,k)*2^(length(base2)-k)

2) Obsolete Increase in loop variable. If you have a for loop, Matlab increases the variable by itself (check the docu). So the following has no effect, since Matlab simply overwrites your changes.

k = k+1

I see! Thank you for your help.
