Please somebody help, loading variables from different matlab files
Hi all I have around 310 .mat files all containing the same variables but for different days. For example one variable is spreadMat which contains spreads for various stocks for all minutes of the day. Ultimately i want to write a code which enables me to aggregate these minute by minute spreads into daily spreads... 29 Jul 2010 15:11

Best OS/platform for Matlab
I think that the question of performance vs. OS does require clarifications. In fact, this question is explicitly stated here: http://www.mathworks.com/support/solutions/en/data/1-18C2A/index.html but it is never answered. I think that it would be valuable if Mathworks spend some time comparing the performance acro... 29 Jul 2010 14:04

I'm in the process of trying to get my new Host-Target setup working again. I'm able to connect to the Target PC from the Host (via the xPC Explorer gui), and the followi... 29 Jul 2010 15:11

cmd line function for Edit->Find Files...
I'm looking for a way to find all filenames in the matlab path that contain a given string or extenstion. This can be done via the Edit->Find Files... gui, but I'd like to do this with a function call and return the results in an array. Simple example: files = findfiles('*.dat') would return all .dat files in the MAT... 29 Jul 2010 12:58

Creating daily figures to match monthly average using cubic spline
I have monthly data (say monthly average temperature as it is something easy to understand and the math is the same), and I wish to create a forecast at daily resolution and the obvious way of doing so is using cubic splines. However the normal spline function has the constraint that the spine curve passes through t... 29 Jul 2010 12:58
