Hello,

Quick question.. I'm trying to get the mean of a matrix (vector) now before I created a function that did it but I thought that it isn't really an effective way of coding. I've been looking at the accumulate function online and wanted to ask if this would work:

```
double Matrix1Mean = accumulate(matrix1.begin(),matrix1.end(),init)/(size_row*size_col);
```

Thanks :)
