Why isn't ddots working while vdots works?
Clash Royale CLAN TAG#URR8PPP
I have the following matrix
usepackageamsmath
usepackageamssymb
$$
M=beginbmatrix
fracpartial f_1partial x_1(p) & fracpartial f_1partial x_2(p) & cdots & fracpartial f_1partial x_n(p) \
fracpartial f_2partial x_1(p) & fracpartial f_2partial x_2(p) & cdots & fracpartial f_2partial x_n(p) \
$vdots$ & $vdots$ & $vdots$ & $vdots$ \
fracpartial f_mpartial x_1(p) & fracpartial f_mpartial x_2(p) & cdots & fracpartial f_mpartial x_n(p) \
endbmatrix$$
which complies nicely. However, in the third line of the matrix, I would like to change the third "vdots" to a "ddots". If I do so, I get the following error:
LaTex Warning: No author given.
(The directory on my computer)
!Missing $ inserted.
< inserted text >
$
I.72 $vdots$ & $vdots$ & $ddots
$ & $vdots$
?
Could anybody help please?

Curiously enough, vdots is also legal in text mode, because it is defined as
DeclareRobustCommandvdots%
vbox%
baselineskip4p@ lineskiplimitz@
kern6p@hbox.hbox.hbox.%
%
This fact should not be exploited, better use vdots only in math mode.
On the contrary, ddots is surrounded by mathinner, so it has to appear in math mode:
DeclareRobustCommandddots%
mathinner%
mkern1mu
raise7p@vboxkern7p@hbox.%
mkern2mu
raise4p@hbox.%
mkern2mu
raisep@hbox.
mkern1mu
%
What happens with your input can be understood once you realize that bmatrix internally uses array, where each cell implicitly has $ at the beginning and $ at the end. Thus in
$vdots$
the first $ exits from math mode, producing an empty formula; then vdots is typeset in text mode and finally another empty formula is produced from the trailing $ and the implicit $ at the end.
With $ddots$ it is the same, but now TeX finds mathinner in text mode and raises an error.
How to cure this? Just don't use $ inside bmatrix or anything that's already in math mode.
Caveat 1. I've seen several pieces of MathJax code where $ seems to be used as a mean to produce “weird” symbols: something like $alpha$ = $beta$ or worse. The code should be $alpha=beta$, of course.
Caveat 2. Never use $$ in a LaTeX document. See Why is [ ... ] preferable to $$ ... $$?
You may also want to increase the vertical spacing between the first two rows.

It only "compiles nicely" if you ignore the error messages. Everything between
$$…$$is already in math mode, so you don't need more$...$around thevdots– alephzero

@marmot LOL fixed it

@alephzero Ah thanks got it; unfortunately I am using TexWorks and when it complies it does not open the window with the error messages, so I was not aware I had any.

You might want to replace
$$ ... $$by[ .. ], add a documentclass,begindocumentandenddocument.– marmot
Dec 30 '18 at 1:58
@marmot I have the begin/end document and document class; I just wanted to show the packages I was using in case it affected the answer. That's interesting, I didn't know that [ could replace $$. I am used to the latter from math.stackexchange. Is there any benefit to using the former?
