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?

As your question is confusing for me, though I have answered the question, hope you can replicate or modify the answer as per your requirements.

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,:)=[]
