How can I calculate the grouped data?

I have some grouped data, and intend to perform an element-wise squaring one by one and find out the minimum of calculated results of each grouped data. The following is an example, but unfortunately it doesn't work.

x11 = [1 2 3 6 5 4];

x22 = [11 12 13 16 15 14];

y(ii) = x(ii).^2;

m(ii) = min(y(ii))

Dynamically naming variables is not a good programming practice - TUTORIAL: Why Variables Should Not Be Named Dynamically (eval)

An efficient method is to store the data in an array -

x= [1 2 3 6 5 4; 11 12 13 16 15 14]; 

%Element-wise power
y = x.^2

y = 2×6

1 4 9 36 25 16 121 144 169 256 225 196

%Find the minimum of each row
m = min(y, [], 2)

m = 2×1

1 121

If the data does not have compatible dimensions for concatenating into a numeric array, consider storing the data in a cell array, and perform operations on the data accordingly.
