ezplot3 and hold bug?
"Surajit Nundy" <sn10(a)duke.edu> wrote in message <9a2ce7$p73$1(a)news.duke.edu>... It seems impossible to make more than 1 plot using ezplot3 in the same axes. Everytime the following code is run, ishold returns 0 even after being explicitly set to on. I'd greatly appreciate a workaround, or a pointer to wha... 29 May 2010 14:38

Index matrix to sparse matrix... saving memory
Latest problem.... I have a matrix NxM that is N indexing vectors. Some of these vectors have very few index values, but they all have to be M long (the largest number of index values) so they are filled with zeros. Turns out I only utilize about 3% of the matrix to valid index values so I thought it would be a "g... 14 Jun 2010 07:19

reading a bunch of data files with non-consecutive file names
Thank you for the alternative way of doing this. Li "David Young" <d.s.young.notthisbit(a)sussex.ac.uk> wrote in message <htrdcp$6mu$1(a)fred.mathworks.com>... I can think of two ways to approach this. One is to use the exist function to check if each file exists - the way you propose. The other way is to use th... 29 May 2010 12:28

reading a bunch of data files with non-consecutive file names
I can think of two ways to approach this. One is to use the exist function to check if each file exists - the way you propose. The other way is to use the dir function to get a list of the files available, and then iterate through this list. The second way is particularly useful if the file names are not organised i... 29 May 2010 12:28

How can I ensure that the 1st saved element always is an SOF character? Please help as I am a novice in Matlab and c... 3 Jun 2010 19:01
