hi friends,
i have an ascii word and its binary state:
x = dec2bin('matlab')
x =
1101101
1100001
1110100
1101100
1100001
1100010
but i do not want this in this way... i want it like an array that is below:
y = 110110111000011110100110110011000011100010
the question is how can i convert x to y?
i tried reshape() function but i couldnt success :(
please let me know...

y = reshape(x',1,numel(x))
transpose first

so can i use y like an array whose dimension 1x42?
the thing that i want to say;
i can an array by randint() function
for ex;
a = randint(1,42);
a is an array and its dimension is 1x42;
now i want y to be like a that is above...

Yup. But I do recommend explicitly putting the number of bits you want in to the dec2bin() call, such as dec2bin('matlab',8)

If you mean that you want the strings to be numbers in an array,
yv = arrayfun(@str2double,y)
