I running the exact same test on the exact same code (ensured by checking out the same revision of a code repository) on a Windows computer and on a Mac, and the test failed on Windows but passed on Mac. I think I've controlled for all the differences between the two environments: in both scenarios.

Here are two possibilities for changing the title of a Matlab window.

I think both are good laptops, and pretty even when looking at performance. Both have the same capability with processer, and ram. If you are close to a Microsoft store, I would side on the surface pro 3, since you would get really good support.

When I have my Dell venue 8 pro, I had to send it to them and was without a machine for a period of time. If you have an issue with the surface pro, and you bought it from one of the MS stores, I couldn't see you being down for anymore then a day. Also, they are having some great black Friday deals coming up. I will be running Split Step Fourier Method simulations of optical pulses propagating through fiber. Also I will be writing my thesis.

Not primarily on the laptop, I have a desktop that most of the work will be done on. I want a laptop that I can take with me without being too heavy but that can also handle some of the simulations.Given I believe MATLAB is pretty resource intensive at times, I would suggest the XPS 13. It may not be a convertible but it is also not very heavy and does offer more room (and fan support) for the processor to cool when under full load. My only hesitation is the fact that the product has Dell in the name.

Every Dell I have used, setup, etc., in the past few years has suffered from significant quality control defects and working with Dell support has always been (at best) annoying. Surface support, which I have also used, takes minutes rather than hours, and the people have all spoken English as their first language.
