Dear primers,

i read in a list of data (which are called roi), then i would like to fit these data (done in this case by a spline function) and compute the values for y=0.3.
for some reason, maple (i am using maple14) gives me only one value instead of two.

i would be happy if somebody could give me a hint how i get both values.

How does one select rows of a Matrix with say column three having values less than 4?

If for example,   

a:=Matrix(1..5,1..5,rand(1..10)):

One way that I know of is to first convert the Matrix to a listlist

b:=convert(a,listlist):
and then you can use
c:=select(b->b[3]<4,b)
then
d:=convert(c,Matrix)

Is there a way to that without all the conversions?

how do i use Maple to prove a+c is congruent to b+d mod n?

Hello,

I was following the Getting Started tutorial wher it shows how to do a Taylor series expansion about z=2, for a 4th degree poly.  Maple returns

error, unable to parse 'mverbatim'

Further in the tutorial it asks me to type (x+2y)^3 when upon pressing enter, it returns the same error.

What can be done to correct this error?

Thanks,

Cary M.

Is it possible to construct a fairly complex Punnet square inheritance matrix in Maple 13?

Suggestions and examples or urls would be appreciated.

How do you find the midpoint of 2 points on Maple? For example, (0,2) and (1,3).

How do I graph a quadratic equation on Maple 13? For example, x^4+x^2=3x^2+8

I was wondering how to find the distance between 2 points on Maple 13. For example points (-1,3) and (4,-2).

Hi,

I have a weird problem I hope you guys can help me with:

When I leftclick on a file type "mw" in Internet Explorer it opens as a xml file.  The filetype is associated in Windows with Maple and in Firefox and Google Chrome it starts Maple and loads the document. How do I get the same behaviour with IE? Im running IE v. 8.

Thanks in advance.

-h

the problem is as follows:

if((a>0) and (b>0) then (c:=2*a, d:=3b, e:=9b.....)

elif ((a<0) and (b>0)) then (c:=.., d:=..., e:=....)

elif.....

.....

else c:=..., d:=..., e:=...

end if

i know i have the if conditions right, but not sure about sequential conditions..what is the correct syntax for this??

I'm getting errors like parse errors, unterminated if, and invalid sequence (on the :=)...

array.mw

if I assign an array to the variable name x via another named array (A) then if I change all of A, x remains unchanged. this is what I'd expect

however if I change just one element of A then x also changes

this is illustrated in the attached worksheet.

Why is this happening? And how can I stop x from changing if I change a single elment of A?

thanks

Hi

I'm exporting arrays of plots as html (so I get multiple gif files). At the moment I do this off the menus (file\export as) is there a way to write this command at the prompt in worksheet mode?

thanks

I am trying to resize some 2D and 3D plots. I find that the following writes a resized plot to the desktop, but it is cumbersome to use in a program when there are multiple plots:

MYPLOT := %:
     plotsetup(jpeg, plotoutput = "/Users/username/Desktop/EXPAND.jpg",

     plotoptions = "height=1000,width=1000");
MYPLOT;
plotsetup(default)

Look here concerning this theorem, which states that in any triangle, the three points of intersection of the adjacent angle trisectors form an equilateral triangle, called the Morley triangle.

Help me find all the lines that are carried out from the origin and perpendicular to the 3-D surface.
