Hi. Is this the expected behavior?

I hope not. I expect A' = [1 2 3 4]

Best regards.

Alvaro: maybe like this ?

Hi Jean. Nope, maybe more like this:



BTW, this is a workaround. I expect this result but for the previous syntax.

Best regards.
Alvaro.

Hi Jean. Nope, maybe more like this:

You just append, my code inserts wherever needed.
My mistake I named Append(,,,)
OK, you are imitating MCD.
Simpler Append: transpose the row, stack, re-transpose.

I'm trying to imitate Wolfram's Mathematica Append.

Not that much miraculous Mathematica 4.0
Mathcad APENDPRN was almost never used.
Useful to compact/file a data set with wisely
collected the fitting coefficients.
On that application, Smath is far superior ... Explain
Smath can save same stuff + the formula ... WOW !

Saludad Alvaro [is that correct ?]

Yes it is correct, or at least it conforms with the general approach of the program (vectors are single column matrices, anything else is a matrix). You might see it better in a 2 rows matrix:


The new indices are added expanding the matrix vertically; there is no special case for single-row matrices.

For your task, one way could be this:



Or this:

...

... append this Jacobian matrix.

Thanks for the explain. You give to me the rule for understand the result. Just as comment, matlab don't follow that, and gives this results:

What Matlab does Smath does as well with lot more user specifics.
Matlab => MDA [Muliti Dimensional Array]
Mathematica => Cell Array
They just have their system. I can do whatever from this example
and very quick too, just few more modules.
