How do I modify the equation serial number and its caption?
Now the equation show the serial number as (7.1).
But I want the string of the caption of the equation as (Eq7.1).
How do I modify the command of equation?

I assumed that you were using book as your document class; of course, you can adapt my example according to your needs.

gmedina,thank you! It works. But how about the matrix?
My matrix does not have the serial number.
How do I add the serial number to the matrix and use the \ref with "{Matrix \arabic{chapter}.\arabic{matrix}}"?
