Hi Every one
In MathCAD 15 I was able to use vlookup referred to the tables inside the worksheet
because any table has a specific name but because in Mathcad Prime there is no name related to table I can not do that at all
I do know How to can do the the same in Prime without using excel
I do not like using excel entire worksheet because every time you have to double click on it & going to another program in fact , it is also take unnecessarily time,
It would be your kind if you find any solution in this regards except using Matrix
I don't understand your question. Your picture shows part of a Mathcad 15 worksheet and all I see here could be done the very same way in Prime, too.
A "table" in Mathcad (15 or below) always is and was a simple matrix - the "tables" G and H you show are matrices. So what do you mean by "except using matrix"?
In Prime there was introduced a way to define a number of vectors in a display they named "table". Its quite unusable for larger data you import as you can fill those table only manually. Basically when you use that tables you have column headers which are the names of the vectors you create.
If you have created that kind of table instead of your matrix G and if you named the columns in that table Gcol1, Gcol2, Gcol3, etc (you sure would chose other names), then you can use
Looks like you have changed ORIGIN from default 0 to 1.
Thanks for your time & answer
it seems I could not show what exactly I am looking for , I tried to attach two new image, as you see here in mathcad 15 we can easily use VLOOKUP
but as you can see I can not do the the same in MathCad prime because tables in the prime does not have any name so I can not define second parameter of
vlook up in there....
I think I understood your question pretty well but adding an example always is a good idea.
A table in Prime just look like one single entity similar to a matrix but it isn't. You had written yourself that you are missing a (variable) name for a table. The reason is that a table is nothing more than a nice display for a bunch of single vectors.
In your table you have defined two vectors with the name a and b (the column headers I was talking about in my first answer. So you could use my suggestion:
"lookup" does exactly what "vlookup" does in the matrix approach. It looks for "C" in vector a and returns the corresponding value from vector b.
What you define with your table are just two vectors and you could as easily have written
to achieve the very same, but less pretty and less compact.
So if you define a second table and again use "a" as column header/vector name, you overwrite the previous one - its just a normal variable, nothing which is "inside" the table and protected. I guess Primes tables are a much simpler concept as you might have thought.
In Mathcad 15, when you chose Insert->Data->table then a matrix is created.
In Prime when you insert a table then a number of single column vectors is created.
