i have this array when i display it or check it in the work space it's approxaimated
till fourth decimal 0.0000 while it has 5 or 6 decimals 0.000000

You are mixing up two different things:
  • how numeric data are stored in a computer,
  • how numeric data are displayed by a computer.
What you see in the command window (or the Variable Viewer, or whatever) is just a displayed representation of the numeric data., it is not the numeric data itself. In MATLAB the Command Window representation can be controlled to show different number of fractional digits or precision, or use various notations: see the format command.
"when i use specific index in the array in an equation it's used with no approxiamation"
The precision of the numeric data stored or used in calculations does not change when you use indexing.
