I have a two-variable matrixfunction A(x,y) with entries A_i,j(x,y).
I want to use mtaylor for each entries and the result to store in a matrix B.
Is it possible to do using the map command?
If not, what methods do exist?
(Instead of typing mtaylor for each entires.)

restart:

dsys := {diff(x(t),t)=y(t),diff(y(t),t)=-x(t),x(0)=1,y(0)=0}:

dsn := dsolve(dsys,numeric):

dsn(1);          [t = 1., x(t) = HFloat(0.5403023317785669),  y(t) = HFloat(-0.8414711011553073)]

After solving  this system I wish to obtain a numeric value to the integral:

what should i do to write matirx of this form in maple  for nth order

[1        4        1                                    ]

[B_-1,0   B_0,0   B_1,0                                   ]

this code executes fine in  M13. but in M15 theres a problem. doesn't like the local.

i wish maple had a compatability/update feature like mathematica...

Hi,

I recently have a problem when I try to use dsolve/numeric to solve an IVP. Suppose we have diff(y,x) = w(y) and y(0) =  y0. We can solve this IVP numerically by dsolve/numeric. In Matlab, we can obtain y and  the derivatives yp using the command [y,yp] = deval(sol,t) at any time t within the range we pre-defined. Basically, matlab ode solvers return a solution  skeleton first, then evaluate y and yp of the other points by a piecewise interpolation which is called...

with insequence=true command, first, the first option is showed, then second, then third and so on.. but i want to show all options from in grpah, then animate in sequence.

could someone help me.thanks

Hi,

     I'm reading in a file as

eigvect:=ImportMatrix("C:\\Users\\Sorted_Eigenvectors_1.txt", source=csv):

but I want to generalize this to 

eigvect:=ImportMatrix("C:\\Users\\Sorted_Eigenvectors_i.txt", source=csv):

where i is a positive integer, I tried

eigvect:=ImportMatrix("C:\\Users\\Sorted_Eigenvectors_%d.txt",i, source=csv):

but this is incorrect. What is the correct syntax?

Thanks!

So i got rhis

Hello, im a current user of Maple 16, i have a problem in finding a minimum of equation ( equation of a external work equating the internal energy dissipation) f= E-W ( im studying a slope stability with limit analysis)

the equation is:

I have a 3dplot of a certain procedure with the color specified by another procedure. 

The standard color range, from red to purple, does not look very good in my application. Is there a way to change the color range to for instance: light green to dark red?

This is a very strange and specific issue I am having with any Windows x86 vm after having installed Maple 17. 

Before installing Maple 17 (and also AFTER installing it, before the reboot), I can open a command window while logged in as the local administrator and successfully issue a command like:

sc config BDESVC start= disabled

After installing AND REBOOTING for Maple 17, if I log in as the local administrator, open...

hi friends i have done with my code but still getting error in summation term. Please help me out. ThanksFractional_(1).mw

Let A be a table. I give following sequence of commands:

>>B:=A;
>>A[x]=34:

Then surprisingly (at least for me) it turns that B has also changed its value for B[x]. Would someone help me understand this? What is it called? How we can stop this behaviour i.e. A and B should behave as independent tables?
