Hello! The mean function from statistics has the “dims” option, which lets me average a matrix into a vector by averaging the rows or columns. Is there a generic way to do this without for loops? Say I want to do the same thing with the dot function, where I have a 1x3 array and a 10x3 matrix and …

[image] Ribeiro: I have a 1x3 array and a 10x3 matrix and I want to do the dot product of the array by each line of the matrix This particular computation is exactly a matrix product, so just doing M * v' will be the best approach. More generally, you can use the eachslice, eachrow, or eachc…
