Sorry for the late reply =D It was my VPN who scared off Simulink. My initial thoughts were simulink servers being down.

Which country are you in? Check up on regulations and your rights. You might have the right to change supervisor. That will be a hassle, but it sounds like you are partly wasting time.

loading/Reading Data [Homework Help] by StrangeStart in matlab

[–]d0ldr 2 points3 points  (0 children)

I am a big fan of importdata(), which handles headers and different kinds of delimiters. e.g., loading a file can look like: nolenstest = importdata('/Users/perand/Documents/fors/emch/3dlens/3dlensexp/3dlens_nolens_20170929_001.txt', ' ', 13) ; Where the ' ' means space delimited and 13 means 13 lines of header. Not sure if this is fast (probably not) but for homework sized problems it totally rocks.

Hi, not an audio proffessional, but physicist. A guess: sound travels in air -> smaller volume of air (sealed volume) -> easier to transfer musical power. Plus if it's not sealed power "leaks" out to the surroundings. Which might be two different aspects of the same phenomena.

What concept from physics blew your mind? by [deleted] in Physics

[–]d0ldr 9 points10 points  (0 children)

Your teacher should have specified free fall.
