So I do have an multi dimensional array in this format:

```
Cjk = [[81 51 31] [82 47 54] [34 55 64] [96 73 43]];

```

How can I get the minimum values on each index of the arrays contained.

I want this output:

```
34 47 31  # these are the minimum values compared to each one values of the same index

```

I have tried some methods but they were unsucesfully because I had to work with I and J because the array Cjk will get more values in time so it needs to be scalable
