[SPRstructur]

Dear all
I try to change from Input to Function

!!!!!! Purpose!!!!
- Delete (1.Old Input) and Put (3.New Input Under Area)
- Correct and add new Variable (a,b) to (2.Existing function) ) and every functions in the area have (a,b) as new variable additionally.

What were you hoping to get when you defined:

And

If a is an array, you cannot use it to define a range like this:

Success!

That you mentioned just for plotting, but that I want the most function in areas if can work is ok 

the output I want 

w(x,y,a,b..)

My(x,y,a,b...)

My(x,y,a,b...)

....

Ant the plot maybe not important for me now 

sorry now I not near computer can not print screen just text only

thank you

I think all you're trying to do is plot your calculations.  See if what I've done to your beautiful sheet helps at all.

I want a and b as variable not Input

Attached is a Prime 4.0 file.  I rewrote your original file into 4.0 (Express at 4.0 leaves a footnote but no splash across the page.) so I could study it; that's impressive work.

Then I understood your request, and have started to see if I could make that work.  I haven't been able to figure out how to create your vector B or the  matrix A as functions.  If we can do that then there's a chance we can achieve what you're after.

Maybe there's someone smarter out there!

And a & b can put as matrix and result still ok
