How do I do recursive rolling average and variance fast?
Hi all, In recursive moving or rolling average, result_t = alpha * p_t + (1-alpha)* result_{t-1}, where p_t is the new arrival... How do we do this fast in Matlab, using the "filter" function format, i.e. it works on a whole array column-wise. Now, how to apply the same concept to rolling variance? I... 5 Jul 2010 14:25

How do you do a moving median fast?
Hi all, I figured out a trick that I can do moving average fast - via "filter" function. But how do I do moving median fast, using the "filter" function format? I.e., the filter function filters a whole array column-wise. ... 6 Jul 2010 10:02

squareform memory issue
Hi, I'm using the pdist function to calculate the distances between a set of points. The results are transformed into SQUAREFORM and the FIND function used to determine the row and column of the minimum nonzero distances (or distances below user-defined threshold). Of course, when the matrix becomes large we have memo... 5 Jul 2010 12:11

multiple assignment of vector elements to variables matlab
Hi everybody, I'm sorry if the question is silly, but I couldn't find in the help nor in the newsgroup. I've a vector v and have to assign its values to different variables, something like: a=v(1); b=v(2); c=v(3); .. .. .. and so on. Is there any easy way to write such a piece of code? Thanks a lot i... 5 Jul 2010 18:52

How to add arc model blockset to simulink library? please help!
Hello! I've downloaded the arc model blockset (developed by Delft University of Technology), but can not add it to the Simulink Library, I mean it can not be displayed in Simulink Library Browser whatever I tried. So what can I do to activate the arc model blockset in Simulink Library? Could someone help me? I appre... 12 Jul 2010 12:55

Storing Matlab Variables in A BLOB column
I want to be able to store Matlab variables as binary data in a BLOB column in a mysql database, then retrieve them. How should I go about doing this? I tried using the fastinsert function like so: fastinsert(connection,{'blob_column'},Variable_To_Be_Inserted) but received a 'mysql syntax error'. What should I... 5 Jul 2010 11:04

fitting implicit equation without local minimum
Hello, My problem is the following. I'm measuring the I V curve for a solar cell. So that, I get 2 arrays (one is V and the other is I). Now I know that the integral Int(I,V)= cumtrapz(V,I-Io) can be expressed as an algebraic equation : Int2=a*V+b(I-Io)+c(I-Io)*V+d*V²+e*(I-Io)² To sum up, Int(I,V) is a 3D curve a... 5 Jul 2010 11:04

Displaying a table
Hello all I've got a problem that I've been unable to find a solution to. I'm trying to display a table in a way that is easy to read part way though a function. I have generated a table which shows the user what changes are going to be made to a simulink model, I&#8217;m then providing the user with a menu to sele... 9 Jul 2010 03:59
