How to assign voltage levels to bit-groups?

I have a bitstream which I have grouped into 3-bits (8-ARY system). I want to assign voltage levels to these bits and plot the graph. I am aiming to assign the following voltage levels to their respective bits:

I am working on a generalization of assigning these voltage levels. For example, if I group the bits into 4-bits(16-ARY system), the voltage assigning would go like this:

How is it done in MATLAB?

Thanks.

See

doc bin2dec

or you can just use a lookup table from storing the string values in an array.

Should 1111 really be 16? What about 15?

[dpb]

Yeah, noticed that. Figured typo or just mistake--he got the 3-bit case right.

Yes thanks! it was a typo.
