Dear All,

I would like to know the easiest way to write data, that are stored in a matrix after a computation, to a file with a specific format. To be more precise, I wish to have the possibility to change the format for a given column.

Here is a trial (output is wrote to the terminal for simplification) based on some examples I found, but without success.

Hello,

I want to calculate the IDs product :

How can a vector A=<2,3> be summed to 5.

hi

so ill preface this by saying my knowledge of DE equations is rusty at best and my knowledge of maple even worse so this may be a stupid question. im trying to model the dynamics of a system and when i solve for the DE equation it's giving me an accleration of zero (plotting a blank graph) when it definitely shouldnt be. ive attached the worksheet. DBM-variablemass_pro.mw

For L a given L-function (such as the Ramanujan-tau Dirichlet series) I would like to compute L(s) at 2.5*10^5 values of s equidistributed in a square region of the complex plane in a reasonably short time (meaning, say, less than an hour.) Is there a Maple function that will do this, either in the original software or available on the web?

I have a rather complicated procedure to solve. All the individual parts of the program are working fine, but when I try to put them together the simulation takes too long to solve. To my knowledge what I'm trying to do is not complicated in it of itself; each system is rather simple. But the whole does not seem to be working or is simply taking way longer than expected or is impractical for the task.

I'm supposed to be doing an integration over a range of 48 (48 hours if units are of interest...

For example, i have the field x*e_x+y*e_y. Is there a command for transforming it into the same field with polar coordinates and polar unit vectors?

Hi,

My E01, E02 and E03 are 3x3 matrix

a:=1:  ##how many times matrix E01

b:=3:  ##how many times matrix E02

c:=2:  ##how many times matrix E03

I would like to write EM:=[E01,E02,E02,E02,E03,E03].

If i change the values of a,b and c, i would like it to change on EM too.

For example, when i change a=2,b=2,c=1 would give me EM:=[E01,E01,E02,E02,E03]

How could i do that please? Please advice.

Hi, i'm trying to write the following, it works and is giving me the answer i want. But is there a way where i can write it in a simple manner? Please advice. Thanks.

Need help doing this asap please :).

Hey Guys,

I'm trying to solve a system of 5 linear equations to get 5 unknowns:

> seconddegree:= proc(a,b,c) 

 if a=0 then if b=0 and c=0 then print ('infinite solutions')  

elif b=0 and c<>0 then print ('impossible')  

elif b<>0 and c<>0 then print (' one solution',x=-(c)/(b))fi;   

delta:=b^(2)-4 *a*c;    

elif if delta=0 then print('double solution',x=-b/(2 a))  

elif delta >0 then print ('exist two  solutions',x1=((-b+sqrt(delta...

I can not solve the system of equations

restart;

eq1:= x^4+2*(3*y+1)*x^2+(5*y^2+4*y+11)*x -y^2+10*y +2=0;

eq2:=y^3+(x-2)*y+x^2+x+2=0;

solve([eq1=0,eq2=0],[x,y]);

Please help me. Thank you.

Hi, i'm interested about parallel programming in maple but i cant find a good tutorial. is there anyone know a good refrence for this topic?
