hihi i've a matrix say a(30,10,5). how can a function (for example histogram) be used to calculate along the first axis, or to create a 10x5 matrix of histograms? wolfgang -- Wolfgang Mueller Phone +41 1 256-9203, MeteoSwiss Kraehbuehlstr. 58, mailto:muw at meteoswiss.ch CH-8044 Zuerich, Switzerland http://www.meteoswiss.ch/ -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-...

...better, generate an array with dimension (K,K,N)). I tried apply, but that did not work. Any suggestions? Thanks! Stephan ## Here is a simple example: u <- matrix(c(1,2,3,4,5,6,7,8,9,10),nrow=2) ## What I want to obtain u[1,]%*%t(u[1,]) u[2,]%*%t(u[2,]) ## stacked together --> 10x5 matrix ## This does not work sq <- function(x)x%*%t(x) apply(u,1,function(y)sq(y)) -- ----------------------- Stephan Lindner University of Michigan

I have a matrix of values... for exemple the matrix could be 100 rows and 50 columns... I would like to resample the matrix to obtain a new matrix -> a 10x5 matrix So i need to calculate a new value for every cell, i would like to use a weightened mean to do this. I explain this thing better: In the exemple the original matrix would be divided into 50 partial-matrix, for every partial-matrix should be extracted a value obtained from a weightened mean:...

useR's, I have a matrix given by the code: mat <- matrix(c(rep(NA,10),1,2,3,4,5,6,7,8,9,10,10,9,8,NA,6,5,4,NA,2,1,rep(NA,10),1,2,3,4,NA,6,7,8,9,10),10,5) This is a 10x5 matrix containing missing values. All columns except the second contain missing values. I want to delete all columns that contain ALL missing values, and in this case, it would be the first and fourth columns. Any column that has at least one real number would remain. I know I can use "mat[...

...pick the best scores. So here are the timings at -l13 very high compression: Encode time: x265 (BPG -m 0): 80ms NHW: 20ms Decode time: x265 (BPG): 90ms NHW: 10ms So with an equivalent level of optimization (x4-5, multithreading, SIMD,...), the NHW Project is 80/20x5=20x faster to encode and 90/10x5=45x faster to decode than x265 (optimized HEVC)! Yes, 45x faster to decode than x265 at very high compression!, this would really save on battery life for mobile devices! Else also, with the new improvements I finally find the NHW Project competitive with x265 (HEVC) on nearly 90%-95% of the imag...

Anyone have any experience with a R510 with the PERC H200/H700 controller with ZFS? My perception is that Dell doesn''t play well with OpenSolaris. Thanks, Geoff
