Concatened matrix

XDN — Thu, 27 Dec 2018 09:31:31 GMT

I want make a program for concatened matrix

for example i want to obtain it:

How make a program for this ?

In this example , matrix 3x3

in final application matrix nx3

Use a combination of the stack, augment and submatrix functions.

Please you can make me an example ?

I don't see how to make it ?

This little program should do the job:

I try it:

XDN — Thu, 27 Dec 2018 12:16:49 GMT

Great !!

i try to understand it

Re: Concatened matrix

It's very well for me

but i don't understand perfectly your algorythm

i try modify it but i no have a sucess

I my final application

First Step

your program is right

Second step

I need to make a matrix M1 with B mark

for example:

0 -5 0

-20 -5 0

0 -5 0

5 -5 0

0 -5 -1

0 -5 0

0 -5 1

And third make a matrix M2 with C mark

for example

0 0 -1

-20 0 -1

0 0 -1

5 0 -1

0 -5 -1

0 2 -1

0 7 -1

See if this does what you need for M1 and M2, making use of Werners function.

Success!

Great Luke

i make a new parameter

to match with werner's algorythm

Now it's right

You are great's people

Thank's for all

Guess here is a solution using just one function. The argument order of the three matrices is vital, though.

Don't forget to close the thread when there is no further question.

since yesterday my problem was update, but's it's very similar

I have some difficult with program

I don't understand perfectly your algorythm

I try to modify it for my new application, but i don't have a sucess

Now, i have a algorythm wich generated 3 matrix.

This matrix are the coordinates points in 3D space axis by axis

X matrix

Y matrix

Z matrix

I need a generated M matrix wich include all 3D coordinates of axis point from X,Y,Z matrix.

And finally i verify it with 3D graphic

for example (here matrix have only 4 rows, in finally we have n rows)

Looks to me like something completely different than what you had asked for before.

Re: Concatened matrix

XDN — Fri, 28 Dec 2018 12:34:52 GMT

Yes ! because my first approach are erroneous

i'm sad

Re: Concatened matrix

Werner_E — Fri, 28 Dec 2018 20:06:50 GMT

So you would have to explain in more detail how the matrix M is supposed to be built.

I your example (n=4) M has 23 rows !?

The values +8.33 and +25 are never used in M.

I would have expected rather either 3*n (=12) or n^3 (=64) lines in M

What about the zeros in the three matrices? Is there always just one column in each of the three matrices relevant?

Could it be that you are looking for something like this:

Sorry for the time to make answer...

Yes ! Zeros are not necessary in matrix

Thanks it's great !

it is that's y want !

Thanks for all ! i learn some things with your example

very thanks
