I thought this would be simple enough, but I can't seem to get this to work...

If I have the following...

> e1 := fsolve({Qd, Qs1}, {x, y});
                       {x = 60., y = 40.}

Then how can extract the appropriate numeric format to plot this point? I keep getting data type errors.

Any help would be much appreciated!

I'm trying to plot an arrow in polar coordinates.  Here's an example for an arrow who's base is at (1,Pi/4) pointing right with unit length.  It seems like the coords option is being ignored by plottools[arrow].

The following lines give me the same results in Maple:

plots[display](plottools[arrow]([1,Pi/4], [1,0], 0.05, 0.1, 0.1, coords=polar));

plots[display](plottools[arrow]([1,Pi/4], [1,0], 0.05, 0.1, 0.1));

Is this a bug?

Hi

My Maple 13 puts small curly brackets to the left side of an expression and this causes several problem for me. What should I change to write good ones? (I mean normal, big brackets, not small brackets to index.) (I use the AltGr+b combination to write a left curly bracket.)

Hi all 

I very very new to Maple so please forgive me if this not a great question.

I'm trying to input the command lfsrlength(v,n) to calculate the determinants mod 2, however Maple is just returning the command and not the determinants please see below

L101;  [1, 0, 1, 0, 0, 1, 1, 0, 1, 1, 0, 0, 0, 1, 0, 0, 1, 0, 0, 0, 0, 1,
        1, 1, 0, 0, 0, 0, 0, 1, 0, 1, 1, 1, 1, 1, 1, 0, 0, 1, 0, 1, 0,

I'm trying to get a blank procedure call to work.  How can I go about doing that?

I wanted to do something like this

changedir:=proc(change)
  if change=NULL then currentdir("f:/") else currentdir(change) end if:
end proc:

changedir()
Error, invalid input: changedir uses a 1st argument, change, which is missing

Hi,

Can someone help me out here, is it possible to select a column from a matrix result in maple.

for example using the Eigenvector(M) command lets say i get the result

How can I find out how many positions there are in a table? 

I have this equation:

When I atempt to solve for this is the answer I get:

 hi

I am new in LinearAlgebra and i have many question in it,

My problem is in this pdf files and i described in it my question.

Hello,

I am using Maple 14 with Windows Vista OS and I would like to ask 2 questions:

1) Is there any possibility to change the width of a slider? I have 2 very similar source codes of the slider (one horizontal, one vertical). I would like to use the vertical one, but the biggest value does not appear correctly. This value should be "1000", but only "100" appears. In the horizontal case everything is OK.

Here are the source codes you can try:

Hello wizards,

I'm given to understand that using add() or if possible Task:-Add() is more efficient than a FOR...DO loop. Today I'm asking about the limits of this generalization. My illustration is probably missing some evalf's, but hopefully the concept is clear:

A computation I'm working on involves between 10E4 and 10E6 computations like

Maple's Statistics package contains many predefined probability distributions; well-known ones such as the normal distribution and lesser-known ones such as the Gumbel distribution. For these distributions, we ship efficient algorithms that can quickly generate a large number of sample points. To generate a sample of size 10⁶ of both of these distributions, and print the time it took to do this (in seconds), you can run the following:

with(Statistics):

Consider the following C code:

Hi, 

How can I create a matrix M by M with maple, where the elements of diagonal comes from b[i]=i+1 and the other elements comes from c[i,k]=i+k.
