This depends on what you mean by "best": fastest? minimal memory usage? hardest to decrypt by brute force? smallest implementation? most tolerant to types of input? most compatible to other applications?
You can implement all known encryption methods in Matlab. I prefer AES, see: FEX: CryptAES.

Who said anything about the size of the data? There are encryption methods that require more than 8 TB to process even small data. And clearly an encryption method that requires custom hardware is "better" than an encryption method that can be run on any common computer.

I disagree: If the method need a special hardware, it is "worse".
In my personal opinion, that "best" method encrypts the input to a vector of zeros by using a very specific algorithm. About another at least "very good" method: http://en.wikipedia.org/wiki/Voynich_manuscript
