When I used [famous internet search engine] and searched for "MATLAB arccos", this is the very first result listed:

You know that matlab comes with documentation, right? How about looking it up in the doc under trigonometry

Use acos or acosd.

Mr.guillaume.. Iam very thankful to you. finally I did what I expected. I think many legends in matlab would have hurt by asking number of questions. Iam very sorry and more thanks.. Thank you again. acosd is right.
