  - by Musa

  Hi, Let's assume that I have a vector r <- rnorm(4) and a matrix W of dimension 20000*200 for example: W <- matrix(rnorm(20000*200),20000,200) I want to compute a new matrix M of dimension 5000*200 such that m11 <- r%*%W[1:4,1], m21 <- r%*%W[5:8,1], m12 <- r%*%W[1:4,2] etc. (i.e. grouping rows 4-by-4 and computing the product). What's the optimal (speed,memory) way of doing this? Thanks in advance.

• Shortcut for moving between Vim windows

  - by Kamilski81

  Let's say I have single Vim tab displaying 9 buffers (equally separated, like a table 3x3). Currently, to get from the top left window to the bottom right one, I have to press 3, Ctrl+W, J, and then 3, Ctrl+W, L. This is cumbersome and I would like to just be able to press Ctrl+9 to go to the 9th window and Ctrl+3 to go to the 3rd window, etc. Is there any easy way I can map something like this in Vim?
