## Generate Surface using PDE Method...

Does anyone has any maple worksheet that generate surface using the PDE method described in this article?  I am trying to learn this method but I am not familiar with the mathematics to do it although the paper gives some description of it.  I hope someone can demonstrate the procedure in Maple.  Thanks

## Error with function using Units...

Maple 18

Please see the attached worksheet for the error at the end, any idea what happens?

Besides, anyone know how to make plot array with each element has a plot and scatterplot in it?  I made my plot by making table first and then type the cmd individually.

Raw Data

Table 1: Compactability Curve

Table 2: Compressibility Curve

 (1)

 (2)

por1(x);

 (3)

 (4)

Target Weight of Tablet, :

 (5)

Tablet True Density:

 (6)

Width of tablet

 (7)

Length of tablet, l:

 (8)

Cup Depth, h:

 (9)

Cup Volume

 (10)

Die cross sectional area, :

 (11)

Equation to solve tablet thickness using tablet dimension and porocity:

Tablet bulk density:

 (12)

Tablet volume:

 (13)

Tablet bulk Density:

 (14)

 (15)

Function for thickness:

 (16)

 (17)

Tablet tensile strength:

 (18)

Break force of tablet (N)

 (19)

 (20)

 (21)

 (22)

 (23)

 (24)

Encounter problem while chaning variable

BF:=

 (25)

 (26)

but por1 works fine on its own with units

 (27)

plot(evalf(por1(xx)), xx = 10 .. 200);

I also used a lot for for loop in this worksheet, can anyone suggest another way of doing it? And I think I initiated many Array(1..3) that is of no use.  But if I do not initiate and do the following

A[1]:=a :

A[2]:=b:

A[3]:=c:

A;

output: A

Only if I initiate A:=Array(1..3) and then define the element I can see the complete A array at the end.

## How to have maple identify dependent var...

I am trying to write a procedure that have the following input:  expr, xdata,ydata. [dependent variables list]

I want a procedure to calculate Rsquare following the method described in

http://www.mapleprimes.com/questions/120014-How-To-Calculate-Coefficient-Of-Determination

But I want the proc to take any abitary function and be able to identify the  dependent variable...how can I approach it? what function can I use to match [dependent variable list] in expr??

Thanks

## Cannot interact with explore component i...

Maple

I have a question regarding maple reader.

It seems like in maple reader, one cannot interact with the output of the Explore function.... which mean I am forced to make my own component if I want to creat application for my co-worker to use..this is some what annoying.  Is there another way around?

please open the attached file in maple player and you will see the output created by Explore gives error message.  mapleplayer_test.mw

.

## Ecountered : Error, unterminated procedu...

Maple

Hi Mapleprimes community,

I am a maple novice and was trying to write a procedure but cannot tell what my syntax error is.  I would greatly appreciate if anyone can point out what I did wrong or any improvement in the code that I can make.  Thanks
