How to find the maximum entry in large array data file gnuplot?

Question

There is a data file data.dat which contains:

1   1   1   2   2   6   1
2   4   1   4   1   7   1
3   1   1   6   1   6   1
4   1   1   8   9   76  1
5   1   1   16  1   1   1
6   6   1   9   1   2   1
7   1   1   7   1   99  1
8   8   1   5   8   1   1
9   1   1   3   1   0   1
10  1   1   2   1   1   1

Using gnuplot we can find maximum value for a particular column (say 4th column) by using

stats "data.dat" u 4

My original file has more than 100 rows and columns, it's a large array of numbers. I need to find the maximum value from the entire array (here it is 99). Is there some trick in gnuplot to do so?

@Christoph Works! stats "data.dat" matrix works too, i.e. without mention of any column. Exactly what I needed, thank you! — Batfan
