Hi all, I have 20 data frames, named frame1, ... , frame20. Each data frame has the dimension 20x5. I need to build a function that calls out the observation in Row 1, Col 2 from all 20 data frames and places it in a vector of length 20. I have tried the following code: vect <- rep(0,20) for(i in 1:20){ vect[i] <- paste("frame",i,"[1,2]",sep="") } The...

Dear useRs, i want to split a matrix having 1116rows and 12 columns. i want to split that matrix into 36 small matrices each having 12 columns and 31 rows. The big matrix should be splitted row wise. which means that the first small matrix should copy values which are in first 31 rows and 12 columns of the big matrix. similarly 2nd small matrix should contain values from 32nd to 63rd row of the

...5.I run the .exe 10x times and I 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 (HE...
