MATLAB parfor is slower than for -- what is wrong?
Hi, the code I'm dealing with has loops like the following: bistar = zeros(numdims,numcases); parfor hh=1:nt bistar = bistar + A(:,:,hh)*data(:,:,hh+1)' ; end for small nt (10). After timing it, it is actually 100 times slower than using the regular loop!!! I know that parfor can do parallel sums, so I'm not sure why t...

Making plot of matrix entries using Matlab
I've got a matrix A=magic(4) and wish to plot the values using plot3(1:4,1:4,A,'ks'). But that plots everything on the diagonal and not where they actually are relative to the other values in the matrix. How do I do that? I'm sure it's pretty easy but I'm new to matlab. ...
problem im motion control with MATLAB
hello i have a problem in motion control in matlab imagine a four bar linkage mechanism like this.as you you know in an ordinary 4 bar linkage we have 2 fix points but here we have just one & the second one it fixed to a pinion (small gear).we have the ratio of gears so we have a relation between teta1 & teta2 teta2 = 5*teta1 (the mec...

MATLAB is running out of memory but it should not be.
I'm trying to do a PCA on my data using princomp(x) that has been standardized. The data is <16 x 1036800 double>. This runs our of memory which is too be expected except for the fact that this is a new computer, the computer holds 24GB of RAM for data mining. MATLAB even lists the 24GB available on a memory check. Is MATLAB actually run...

Tiling matrices in matlab
Hi, Here's an interesting question :) I have two "vectors of matrices" which I want to tile like the hankel function does for regular vertices. For example: Column Vector: 10 00 20 00 30 00 Row vector: 30 40 50 60 00 00 00 00 The resulting matrix needs to be: 10 20 30 40 00 00 00 00 20 30 40 50 00 00 00 00 30 40 50 60 00 00 ...

Calling (or running) a simulation software from Matlab
I have run simulations on software (named CMG) using command prompt. The command prompt works well in all respect of running the software as well as generating reports and output files. To generate an ouput file (.rwo format) containing the desired result, we have to run the executable of the report program which uses a parameter file (....
MATLAB: why would an axis have its position property changed?
I'm working on a custom plot on top of which I add a second blank axis object to show a secondary scale on the right hand side of the graph (as well as the primary scale on the left hand side). Works great (and had been, for years), until I tried it again recently in R2010a and for some reason the primary axis gets its Position propert...
