Suppose I have 1000x1 matrix and my data is from (50,60) and then from (160,170) and so on (i.e randomly distributed), What I want is to find maximum out of this 50 to 60 location and then maximum from 160 to 170 location and so on. How to find this ?

yes these locations are stored in another matrix

Suppose mat is 1000x1 matrix
%this will give the maximum value within the matrix uptp 50 rows and 60 colm
mat1=mat(1:50,1:60);
max1=max(mat1(:));
You can do the same form other also
mat2=mat(1:160,1:170);
max2=max(mat2(:));
Is this you are looking for?

Hello Sir this piece of code almost solved my problem As I have found all the maximums but one doubt is how to assign the location's of these maximum to another matrix ?

The second part of comment is not clear for me.
Are you looking for this one?
mat_other(r1,c1)
%..........^ index values from first matrix having maximum value
