Hi,

 

I have ZeroMatrix(33)

How do I ask Maple to give me a big matrix form instead of just stating "ZeroMatrix(33)"?

[0 0 0 0 0 0 0 0 0 0.....]

[0 0 0 0 0 0 0 0 0 0.....]

[0 0 0 0 0 0 0 0 0 0.....]

..

Hi, I'm trying to have my half circle divided into equal gaps of 33 , but am not sure what to use. I tried using Array, Sequence, Matrix... But don't think i'm doing it right. Here is what I have :

gap :=pi/(16*2)

I want a sequence of [0,0.0982,0.1963,0.2945,0.3927etc] in a vector form. May I know what is the proper way to do it please?

Many thanks.

 

Hi, I have a formula with variable unknowns, lets say p,q,r.

How do I get the answer giving me the output for different combination of input that I'm inserting?

For example : f(p,q,r):=(34p9-7q)/r

Calculate when (p=2,q=8,r=7) and (p=3,q=0,r=3) and (p=4,q=1,r=9) and so on...

Please advice. Many thanks

Hi I have a number of 3x3 matrix which i want to combine into one big matrix. But I need to add the end of the first matrix with the start of the second matrix, the end of the second matrix with the start of the third matrix and so on, forming a big diagonal matrix. May I know how can I do that?

for example : my Matrix will need to consist : M111M112M113,M121M122M123,M131M132

Hi, could someone please help with this problem that i'm facing please?

This is that I have :

b2:=zeta->[-y(zeta)      -x(zeta)]%T

N0:=zeta->[(1-zeta)     (zeta)]

Basically, the first one a 1x2 matrix, second one a 2x1 matrix. I'm trying to do a dot product on it expecting a scalar answer.

I need to find : B2:=zeta->be(zeta).N0(zeta)

It takes like 5 minutes before this statement comes out : "error, ...
