rank of a matrix.......
how to find rank in a shrtcut way
see by an example.................
1.....2.....3.....0
2.....4.....3.....2
3.....2.....1.....3
6.....8.....7.....5
now see the digits wich are repeating
here 2(4 times) and 3(4 times)
so rank is no. of repetitions of larges digit (here three)
so rank is four
if no repetition then
rank = (sum of elements of primary diagonals) - (sum of elements of secendary diagonals)
hope u find these cool

consider this
3.......6........3..........4
2.......1........3..........7
3.......2........3..........9
1.......3........8..........3
here 3 is repeated 7 times...........then is the rank 7?......... for a 4 X 4 matrix the maximum rank possible should be 4

primary diagonal like here 1+4 +1 +5
and secendary diagonal is 6+2+3+0
here don't apply coz here is repitition
and secendary diagonal is 6+2+3+0
here don't apply coz here is repitition

theese are for those qs in wich repitition is (n+1) times only
where n=highest order
eg. 4x4 then n = 4
max. rank can be (n+1)
where n=highest order
eg. 4x4 then n = 4
max. rank can be (n+1)

3 has max power.....so rank is 3
3 has max power.....so rank is 3
