Deleting rows in a matrix based on a column's value

I have a 17 X 65536 matrix. I need to delete all rows in the matrix who have a value in row 17 less than a certain value and greater than a certain value. How do I do this and create a new matrix?

Here element value less than th1 and Greater Than th2 at clom. 1

 A(A(:,1)<th1,:)=[];
 A(A(:,1)>th2,:)=[]

Below code delete all rows having the first colm element less than 4

A(A(:,1)<4,:)=[]
