A plot command with the only argument of

used to work (up through version 15).  With 16.02 Maple produces nothing but axes.  It is still smart enough to use its default range for the x-axix and to figure out an appropriate range for the y-axis, but it cannot (will not) draw the curve.

If I were a student wanting to...

Dear friends

I solve a rectangular system of equations AX=B   where A from order 3m+1x2m      X from order 2mx1       B from order (3m+1)x1   where  m=400, by LeastSquare or by multiply by A^T  

A^T*A*X=A^T*X

let M=A^T*A

then     M*X=A^T*X                 finally               X=M^-1 * A^T*X

Dear friends.

How can i increasing or removing the software limits for maple 16.

Hi!

How to solve attached equation in Maple?

Is there a possiblity to solve using units?

PS

Solution was done in Mathcad

Hello every one,

I have a question about summing data from an ode.

ode:=diff(T(x),x$2)-T(x)^2=0;

bc:=T(0)=1,T(n)=0;

n:=3:

Thanks

Hi every one

I was wondering whether is it possible to make a subzone plot with in a zone or not?

some thing like this

 Thanks

Hello everybody,

I just realised Maple is allowed for my upcoming exam after New Year.

My plan is to have templates of the most common math problems, I might encounter for quick solutions.

Anyway, I have run into a problem with Laplace shifted data, particularly initial value problems. I have been searching for HOURS, and feel like I have look up everything on google, maplesoft and other sites without succes.

I hope some of you are able to help me. The exercise is:

Hey guys,

I installed the 64 bit version of Maple 16, but it's still running as "maple.exe*32"? There is a similar quesion somewhere here...but this hasnt solved my issue...

There is no more Maple-software installed on the notebook. The other maple-tasks (mserver.exe) are running in 64bit-mode...

some specs: Thinkpad W520, i7-processor, 8GB RAM, Win7 (64bit)

Merry Christmas! :)

Hello everyone,

I have data in Excel sheet. I want to make the data smooth using cubic spline. 

My try can be found in the attached maple sheet. In my try, i was unable to see the

difference bewteen the exact data and the interpolated data. Please have a look and

help to smooth the given data in the attached Excel sheet.

This example was reported to me after a Calculus II student encountered this ridiculous result:

f := (k+5)/sqrt(k^7+k^2):
Int( f, k=1..infinity ):
% = value( % );
             /infinity                              
            |              k + 5                    
            |          -------------- dk = -infinity
            |                   (1/2)               
           /1          / 7    2\                    
                       \k  + k /                    

In the name of God,

Hello dear experts,

I have a nonlinear multivariate system. By running fsolve and with the same initial values, 2 times, at the first time it yields the result but at the second time it doesn't solve. All of the settings in the both fsolve executions are the same.

Do you have any idea?

Best regards,

Hi all,

I read the help on using parameters, then I tried to modify the example

f := proc(a, b, c)

    if _params['b','c'] = NULL then
    a
    elif _params['c'] = NULL then
    a + b
    else
    a + b + c

    end if

end proc:

I can't really spot where it went wrong, but it just wouldnt execute as I would expect...

Hi all,

A := [[1,2],[3,4]];

A1:=convert(A, Matrix);

I am very happy with conversion between Matrices and Vectors.

However, I does not seem to be able to do this backwards to [row] or [column] Vectors???

Say how do I get back to A from A1???

I tried to use

convert(A1,Vector);

convert(A1,Vector[row]);

convert(A1,Vector[row],2);

And many others...

Hi all,

Toy example

myproc:=proc(a,b,c) a*b*c; end proc;

myproc(1,3,4);

myproc(2,3,4);

myproc(5,2,1);

is there a way to input all these together? say myproc({1,3,4},{2,3,4},{5,2,1});

and then get an ouput in the end (list, Vector, array or whatever sensible format)

I remember seeing an example of doing that somewhere, but couldnt find it again...

Thanks!

Hi all,

Is there an easy way to find first and last entries of a vector which is non zero?

fa:=proc(x)
local i;
while x[i]<>1 do
i:=i+1;
end do;
end proc;

fa(<1|0|0|1|0|0>);

That does not work. I have also tried to use

while 'x'[i]<>1 do

keeps getting error saying: Error, (in fa) bad index into Vector

What's the best way to get result 1 (in this case...
