I have a matrix A. I would like to create a column vector B that is
for each row, take a difference between every possible pair of two elements in the row and returns the maximum difference
For example, if A= [1 3 6 7 10], then B=[9]. Please advise a compact way to drive B.

Perhaps a simpler solution which only requires a sort:
A = [1 3 6 7 10];
A = sort(A);
B = A(end) - A(1);
B =
9
Example 1:
A= [6 3 324 2 123];
A = sort(A);
B = A(end) - A(1);
B =
322
Example 2:
A = [111 34 88 11 12];
A = sort(A);
B = A(end) - A(1);
B =
100
