Write a function in matlab called stats that accepts an nxn matrix. this function should compute the following for each column and return 5 row vectors - mat_mean, mat_median, mat_min, mat_max and mat_std_dev which contain the mean, the median, the minimum, the maximum and the standard deviation values for each column in the nxn matrix.

for example:

test result
a = [1 1 1; 3 4 5; 8 10 12];
[mean_a median_a min_a max_a std_dev_a] = stats(a);
disp(mean_a)
disp(median_a)
disp(min_a)
disp(max_a)
disp(std_dev_a)
