I have an array of one row and 163495 columns. The values in this array range from 0-160. I am trying to find the indices that the values are from 69-72. When I use the find x==69, it computes out an empty array.

It works for any integers (0 and 160 in this case) but I cannot use it for any non-integers

i = find(x>=69 & x<=72);;

My suggestion should work for both integers and non-integers. As a demonstration, try:
y = 60:0.3:80;
i = find(y>=69 & y<=72)
y(i)
Your result seems to indicate that x contains no values in the specified range.
Are you sure x contains what you think? Try, e.g.;
x(1:100)
to see if the values look right.
