Numbering matrices in Latex

[Guest black_duck]

Does anybody know how to number matrices in Latex, it should follow the equation numbering, so I can effectively refere them.

 

Many thanks

Is this what you are looking for?

Yes, but I would also like to add the number of matrix, I mean, that if first I have an equation, latex would show it as eq. 1,

 

y = 34x (1)

 

then it would go the matrix,

 

(1 2 1)

(0 4 1) (2)

(0 0 1)

 

and finally another equation,

 

x = yz (3)

 

so my problem is that latex is not numbering the matrix as (2), therefore, the last equation is numbered as (2) when it should be (3).

It shuold be possible to use an array within an equation environment. Or just define your own numbering. Any decent intro to latex will tell you how, though asking people here to regurgitate it would be probably a waste of time given the Tex users groups that exist and all the online resources.

You were right Matt!,

 

I used the equation environment and it worked.

 

Many thanks to both of you, your comments were really helpful and they helped me to solve my problem.

If you want multi-line stuff for things like systems of equations, you can use the equation environment along with the array environment.
