Hello, anyone know how to convert a word to 8 bits binary number ?

For example:

Here is my code:

message:=Hello
m:=convert(message,bytes);

>m:=[104,101,108,108,111]

with(Bits):

for i from 1 to 5 do:
mb[i]:=Split(m[i]);

end do;

>mb[1]:=[0,0,0,1,0,1,1] mb[2]:=[1,0,1,0,0,1,1] mb[3]:=[0,0,1,1,0,1,1] mb[4]:=[0,0,1,1,0,1,1]

  mb[5]:=[1,1,1,1,0,1,1]

Anycommand can add additional one column when split the words into binary to form 8 bit in each row? Any help will be highly appreciated. Thank you.

 How get another solutions ? f:=exp(x²*(a-x))

Hi,

I would like to start using maple workbook to manage my projects but i can't figure out the paths. suppose i have a workbook named: WorkBookTest.maple

and inside this i have a folder containing Data in which i have an excel workbook DataTest.xlsx

and also i have a folder containing Documents in which i have a maple worksheet Document.mw

and also i have a folder containing Code in which i have a mathematica notebook Code.nb

Now inside the maple worksheet, to import the excel data i use the command: Import("this:///Data/DataTest.xlsx")

and it works

Now inside the mathematica workbook, to import the excel data i use the command: Import["this:///Data//DataTest.xlsx"]

and it fails

so if i have other program like mathematica notebook inside maple workbook that wants to call a file with data, how should i define the path?

Does Maple have something similar to c-means clusteirng in Matlab?

 How would I go about doing something like this in Maple?

The docs for the package geometry say:

I am new to Maple. What is the abbreviated form of the distance command?

aa3 := Normalize(<<aa2[1,1],aa2[2,1],aa2[3,1]>,<aa2[1,2],aa2[2,2],aa2[3,2]>,<aa2[1,3],aa2[2,3],aa2[3,3]>>, Euclidean);

the result is one column

how to normalize to a matrix form?

I have a problem with finding a interval where parametr "a" is changing.
My funcion:

                 exp(x²(a-x)) for xcR.
I did this, and I don't know what's next.

g:=x->exp(x²(a-x));
dg:=diff(g(x),x);
solve(dg=0,x);
                      0,2/3a
g(0);
g(2/3a);

Hi, all. I need to built a user interface for my program. First, I create two label and two text area for both the value of x and y. After that I assign a button to random generate the value for x and y within the range with x <y. I write the code below into click action of the button.

use DocumentTools in

Do(%x=RandomTools[Generate](integer(range=1..7);

Do(%y=RandomTools[Generate](integer(range=1..7);

while %x>= %y do

Do(%x=RandomTools[Generate](integer(range=1..7);

Do(%y=RandomTools[Generate](integer(range=1..7);

end do;

end use;

This code can generate two random number and insert inside the boxes created. When the button is clicked, two random number generated but the error dialog box shown on the screen with message : Error in component button with caption "generate" cannot determine if this expression is true or false: %y=%x. What I want is only the true value of x<y will be inserted to the text boxes. 

Any suggestion? Any help will be highly appreciated. Thank you.

For example,

I have original bit :=[10000000]. after encryption by using technique cryptography, I get thecipher text:=[11110011]. Then I need to measure the total flipped bit in the cipher text with the original bit. Have any method can calculate the total flipped bit? Can someone help me? Thank you.

For example, I havd matrix m:=[0 1 0 1 0 1 0], I want to convert it back to m:=[0,1,0,1,0,1,0]. Can someone help to solve? Thank you.

Hi all, 

I have two inter-related expressions of the form,

(i) T=f(w)

(ii) E=g(w)

where the limits of w in both expressions are same. Now I need to plot a graph T Vs E. 

Any suggestions???

Hello Mapleprime Community,

Would you be kind to help me with the attached Maple worksheet. My goal is to do a 2D interpolation given the value of SR (slenderness ratio) and E_G (Young's modulus / Shear modulus ratio) in the Matrix table Vert_Coeff with header as vector E_G and the other as vector SR. I’m confused as to how to do the interpolation. Please help.

Regards,

Moses

So, I have the following inputted into Maple 2015, but the plots are not displaying.  I've double checked the syntax, but I don't see anything wrong.  Any thoughts?  Thank you!

plot3d(cos(theta)^2, phi = 0 .. 2*Pi, theta = 0 .. Pi, axes = BOX, style = line, grid = [50, 50], view = [-1 .. 1, -1 .. 1, -1 .. 1], coords = spherical);

Trying to plot that here actually displays the plot, but it isn't showing up in my Maple worksheet.

hi

how pdsolve 2D couple  non linear differential equations which attached below?

I need to receive a plot of the next equation:

E:=0.001;

eq := E*(diff(y(x), `$`(x, 2)))+(x^2+1)*(diff(y(x), x))-x*(x-1/2)^2 = -x^2+2.7^x ;

/*(x=0..1, y(0)=-1, y(1)=0)*/

I try to use DEplot in such way DEplot(eq, y(x), x = 0 .. 1, y = -1 .. 0); but i always get a bug like 

Error, (in DEtools/DEplot) cannot produce plot, non-autonomous DE(s) require initial conditions.
