I have a matrix A= [1,2,3,4,5,6,7,8,9,10,11]. I would like to find out total number of elements which are greater that 3 and less than 10. expected answer is no of values between 3 &10 is= 6.
I have used formulae no of values =sum(A(:) == 3<A<10)); but it showing error.

you were close:
>> A= [1,2,3,4,5,6,7,8,9,10,11];
>> sum(A>3 & A<10)
ans =
6

sum(3<A)-sum(A>=10)

Michael Haderlein's solution is more robust and general solution, e.g. it gives the correct result (zero) when the bounds are swapped:
>> sum(7<A)-sum(A>=5)
ans =
-3
>> sum(A>7 & A<5)
ans =
0
