Efficient convertors between binary and decimal numbers

Alternatives to the built-in functions bin2dec & dec2bin, exhibiting a somewhat faster performance.

These programs were developed for fast conversions between binary and decimal integers (there are other programs by fellow Matlab-users, dealing with fractions). They can be useful when the binary numbers are in vector form instead of strings.

b2d takes a binary number in the form of an array and calculates the equivalent decimal one. Nothing fancy, but quite effective as a component of a program that needs to be efficient in terms of computational overhead.

d2b is the symmetrical program, taking a decimal number and providing the equivalent binary one, in the form of an array.

Usage: y = b2d(x), y = d2b(x)
