Hello,
I'm trying to write a function which is calculating a B-Spline Function. Given is a knot vector U=[u₁,...u_m]. What i want to calculate know is the basis function of degree 0 which is defined by N_i,0(u)=1 if u_i <= u < u_i+1 and 0 otherwise. I tried to do this with two procs which are leading to the same problem:
procVec1 := proc (U)
m := nops(U);
N := [seq(0, i = 1 .. m-1)];
for i to m-1 do

An analog clock shows the time is 1:15:00.What time all the three indicators are going to meet each other?

kindly help me in defining 99 functions using a do loop... each function contains 99 variables... say y1, y2, y3,...,y99

Hi,

I am new to Maple (Version 17) and got some trouble with the solve command:

The Problem is, that Maple does not find a solution, allthrough there is one :-)

If i put a:=Pi/4 before the first commad, I get one solution, but i want to find the solution in dependence of 'a'.

Also i tried to remove the last equation (a>0...

How to find the sum of the series

sum((x^(3^n)+(x^(3^n))^2)/(1-x^(3^(n+1))),n=0..infinity)

under the assumptions x::real, x<>1, in a closed form with Maple?

it solve result in numeric but not in terms of t, why and where is t?

restart;

equation1 := subs(x=0.5,-(t*x+(1-t)*x+2*x)/(t*y+(1-t)*y+2*y)) –(1-exp(y)) = 0;

equation1fixedx := solve(equation1, {y});

restart;

equation1 := subs(y=-0.1,-(t*x+(1-t)*x+2*x)/(t*y+(1-t)*y+2*y)) –(x+0.08) = 0;

equation1fixedy := solve(equation1, {x});

Hello everyone,

I am trying to solve a system of odes but it takes too much time to excute.

I have attached the sheet. Please have a look.

I want to remove a new (unintentionally created) Mapleprimes account so that I can change the email address of an originial account to my new address which is the address now attached to the new account.

I can find no way to do this. Does anyone know how?

Hello!

I'm new to Maple and I was wondering how to input and solve a piecewise function composed of (1) three functions, and (2) more than three functions.

Txs in advance!

I have been solved a optimization problem by

Hi all,
I plot a cube using the command

with(plottools);
cube := cuboid([0, 0, 0], [1, 1, 1], color = black);
plots[display](cube, scaling = constrained, axes = boxed, style = wireframe, thickness = 3, orientation = [40, 75]) 

Now I would like to plot with different colors some of the faces/edges of the cube? How do i do it? Is it better to use a different code for the cube itself?

I upgraded to Maple 17 from Maple 16 today and I noticed that all of the sudden I can not enter the } symbol anymore although the { symbol works just fine. (I have an azerty keyboard so those keys are AltGr+0/ctrl+shift+0 and AltGr+9/ctrl+shift+0 respectively). My solution right now is to enter the symbol each time via the fences panel, but  since it's a commonly used key this isn't really optimal. 
Does anybody know what causes this and how I can fix this? 
Thanks!

In a "If" conditional statement, maple returns

Error, cannot determine if this expression is true or false: 1.551691464 < (5/6)*Pi

Maple has a number of protected names that cannot be redefined without some work.

A common request is to use the letter j or J instead of the default I for the imaginary unit. Also common is to be able to use the letter I as an ordinary variable, rather than as an imaginary unit. For this, there is a very convenient interface command.


restart;

(-1)^(1/2);

Hi,

I have tried to solve a simple cappilary expresion but I'm not sure...
Please look for ODE, describing in the eq10.
Further I can't explain ln(-hmax).
I will be appreciated for any help.
