why bitand function is not running even i specified the assumedtype value still error comes

for i = 1:2^samples-2
    j = bitset(bitshift(i,1),1,bitget(i,samples)); %rotate left
    numt = sum(bitget(bitxor(i,j),1:samples)); %number of 1->0 and 0->1 transitions

      if numt == 2  %Uniform pattern
          n=sum(bitget(i,1:samples)); %Number of 1-bits
          c= bitcmp(j,'uint8');
    b=bitand(i,c,'unit64');
          r=find(bitget( b,1:samples)); %Rotation index of the bit pattern
          r=mod( floor(n/2)+r , samples);

          index = (n-1)*samples + r;
          table(i+1) = index;
      else %Non-uniform
          table(i+1) = newMax - 1;
      end
  end

Here samples=8;

uint64 not unit64

[Guillaume]

Considering that c is limited to 8 bits, might as well make that uint8 for the bitand as well.

Note that j should be limited to 8 bits prior to the bitcmp otherwise bitcmp will throw an error for larger i (e.g. when i = 207), so:

j = mod(j, 256);
