The main problem with this equation is that the bracket sizes don't match
up.

Following your method (I think!) gives this which is not what I need --
the [{}] need to open on the first line of the matrixed-bit and close on
the 3rd line of the matrixed bit as the above equation does.

Try this one (I only modified the first equation). The two tricks used
here are
- \vphantom{\int_a^b} procuces a vertical space (0 width) which height
is exactly the height of its argument. Assuming that the integral is
what forces the ] size, it gives the right result.
- \hphantom{z+\exp[} does exactly the same but produces an horizontal
space.
More tweaking might be needed for this equation, but I think it
explains the trick. There is also a \phantom{} which sets both height
and width.

I do not think you are going to be able to accomplish what you want... at least, not by using clean, effortless code. :) I tried such things as nesting a matrix with hard-spaces in some cells (so as to make them invisible, but still have brackets expand to encompass them)... but I don't think you can have your opening and closing delimiters match each other precisely in this way. Maybe someone who actually knows some (La)TeX can tell you how to "cheat", as I think this is what you'll actually have to do.

I have followed your instructions but I cannot get it to give the O/P I need.
I have attached a demo .lyx file to better illustrate the point. Do you have any
more suggestions?
Thanks again.

You should be able to achieve something of the sort by doing this:
1. In the Math Editor, type out "f(x)=x*2" (or \times or \cdot or
whatever).
2. Now, go to the Math Panel and open the Delimiters dialog; set the left
and right delimiters to whatever you need, and hit Ok.
3. Within the delimiters you just inserted, insert a Matrix with however
many rows and columns you want... in your example above, you'd probably want
two columns so you could left-justify your terms, but you could just use one
column if you're not picky. The delimiters will grow to surround the entire
matrix. You can even nest matrices; they look odd in LyX, but the printed
output will still be nice.
Have fun,

Formatting of multiline equations
Dear All,
I am having difficulty formatting & justifying multiline equations
in LyX (1.0.4). I want to spead across, say, 3 lines, an equation
containing at least one nested level of parentheses. eg. Illustrating my
point using the fixed font of this mailer I am trying to get something
like,
f(x) = x*2 (z+3{aterm +
another_term +
a_third term})
I would like to make Latex use a 'largish' round-bracket & brace - as it
would if my equation was all on a single line. How can I do this??
TIA
Tom.
