A=[0 0 0 0 1 1 0 1 1 0 1 0 0 ............so on] I wana to convert it into decimals. though i use function B=bin2dec(A, 8). but it returns me error. i wana to convert each 8-bits into decimal number. plz help me how should i do it. Thanks

sum(bsxfun(@times,reshape(A,8,[]), 2.^(7:-1:0)'))

or
reshape(A,8,[])'*2.^(7:-1:0)'

Good catch. Much better.

Same without transposes:
2.^(7:-1:0)*reshape(A,8,[])

bin2dec takes a binary string as input argument.
So you can convert A into 8 bit strings and then call bin2dec
For example A1 = '00001101' B1 = bin2dec(A1)

variant
bin2dec(num2str(reshape([A,zeros(1,8-rem(length(A),8))],[],8)))

bin2dec(char('0'+reshape([A,zeros(1,8-rem(length(A),8))],[],8)))
