Why isn't ddots working while vdots works?
I have the following matrix
usepackage{amsmath}
usepackage{amssymb}
$$
M=begin{bmatrix}
frac{partial f_1}{partial x_1}(p) & frac{partial f_1}{partial x_2}(p) & cdots & frac{partial f_1}{partial x_n}(p) \
frac{partial f_2}{partial x_1}(p) & frac{partial f_2}{partial x_2}(p) & cdots & frac{partial f_2}{partial x_n}(p) \
$vdots$ & $vdots$ & $vdots$ & $vdots$ \
frac{partial f_m}{partial x_1}(p) & frac{partial f_m}{partial x_2}(p) & cdots & frac{partial f_m}{partial x_n}(p) \
end{bmatrix}$$
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?

@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.

@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?
