Title: FIx some bugs, improve precisions and simplify a code.

Fixed Bugs
* nsabsamples had no effect on a quality of an image.
* fimg was declared with a save attribute.

Improve precisions
* More precise value for the PI.
* Use dble(Int) or append _REAL64 for constants.

Simplify a code
* Use intrinsic functions and built in functionalities.

A new Problem
* Performance is degraded by a commit c17576403d7e3384a8a0cc79be08fa853975b126.
matmul function added by this commit slows down the performance.
