Question

grid function grid(i,j) - new function for Mathcad

-the grid in Mathcad workspace have anyway addresses of placed equations, so those addresses from the nodes of the grid could be used also to define dynamically and directly some values

If in one position of the grid (i1,j1) exist a equation exist a equation with lets say the equality T=a+b

Then grid(i1,j1)=T

-so grid(i1,j1) is an alternative way of represention of variable T in next equations

-asume that just on the nodes of the grid are inserted values

-then each value x(i,j) inserted on the grid will have a address

-bye the function grid we can get the value in the indicated position (i,j) by the function grid(i,j)

What would you do with such a function if you had it?

And why is this posted in the members showcase section? There's a whole range of Mathcad forums it could have been posted in.

Hmm . I am surprised u ask this. Now are in development new versions of Mathcad. Now is time to proposed as much of possible development tools.

Then for what else is this PTC community ? To talk about families ?

Function grid(i,j) help to get directly numbers, equations from workspace of mathcad.

Is something closed to what you see in Excel. A cell A8 is a address of a cell. But inside the cell is lets say a number 36983. Then if further u use A8 in formulas then in fact will be that number 36983.

Same thing i want to see in Mathcad. Is a verry simple tool.

If i write somewhere in the mathcad workspace the value 9008 in the location (60,100) then grid(60,100)=9008

Further I can use that number 9008 just by its location. Is a vectorialization and of the tools that Mathcad could use, working in more dynamic way.

That's because Excel doesn't have assigned variables in the way Mathcad does. If I have

T:=432

I can access the value of T without needing to know where it is on the page. That's the whole point of assigning it to a variable.
