## Common Matlab Trickiness

- In matlab, vector and matrix indices start at 1 (not 0). For example, to access the first element in the vector x, use x(1). If you are familiar with other programming languages such as C or C++, this might cause some slight difficulties in the beginning.

- The transpose operator ' (apostrophe) acts as a Hermitian transpose. The Hermitian transpose takes the complex conjugate as well as the normal transpose of a matrix. To take avoid taking the complex conjugate you can use .'

- Sound I/O on matlab is pretty basic. For the linux machines, audio will sometimes be a problem if: a web browser is playing audio, JACK is running, some other audio program is locking the audio resources on your computer.
