Using instrhwinfo() multiple times in one session Hi all, I'm trying to write some code that detects serial devices attached to the computer. It needs to be cross-platform so it must be robust - can't hardcode /dev/ttyUSB* or COM* into the serial port names for handles. I'm using instrhwinfo('serial') to get a list of available ports, so the assignment: hardw... 13 Aug 2010 00:36
Numerical matrix with text headers This is a question about combining text strings and numerical values in the same matrix. I would like to create a matrix of numerical data, with row headers. I've been trying to preallocate the matrix, and am running into difficulties with defining the right type of structure in the right cell. This is my current co... 13 Aug 2010 00:36
Large Sparse Matrix Rank I have a 408,789 x 89,534 sparse matrix with 21,390,749 non-zero elements. Any idea what the fastest method is that will compute (or estimate) the rank of this monster? (Hopefully using sparse matrix calculations.) Most methods run out of memory - I have 16GB total to work with. Anyone ever hear of a trick to ... 12 Aug 2010 20:16

reading avi file to matlab - grayscale issue Hi, I'm reading AVI files into Matlab. I've encountered something strange - the movies are in grayscale format, but when loaded into Matlab, each frame appears like it is composed of R,G,B, where the three matrices are identical for each frame. I worked on the frames, and removed the redundant G,B frames for each... 12 Aug 2010 19:10
Turning a matrix to a single vector ? Hi guys, I was wondering if someone could suggest a way to turn a matrix to a single vector in matlab (ie is there a function?) efficiently. I was using “for” statements (& and looping for the dimensions of the matrix) but with a lot of data, the runtime is excessive. Basically what I want to do is... 13 Aug 2010 01:41 |
