Large matrix error compilation in latex

Question

I am trying to generate a really large matrix but for some reason, I get an error when I try to compile it, Can someone help me to figure out why?

You need to increase the maximum number of columns, e.g. by saying \setcounter{MaxMatrixCols}{20}, see this answer. — , Jun 14 '18 at 05:07
Please don't write \boldsymbol{\mathrm{...}}. (Your matrix features 242 [!!] instances of this atrocity.) Instead, please write \mathbf{...}. Your code will instantaneously become a lot more readable. — Mico, Jun 14 '18 at 06:19
@marmot - Recommending \setcounter{MaxMatrixCols}{20} -- or \addtocounter{MaxMatrixCols}{1} -- would provide the OP with a bit more information about the nature of the problem and about how it can be fixed. — Mico, Jun 14 '18 at 06:28
@Mico Well, I provided a link to an answer where there is some explanation. — , Jun 14 '18 at 11:50

The problem was solved after adding the extra line suggested by the user marmot, \setcounter{MaxMatrixCols}{20}.

is this entire matrix bold? in which case remove all the \boldsymbol and put a single \boldmath before the equation — David Carlisle, Jun 14 '18 at 07:43
@DavidCarlisle - Naaa, there are 121 [!] instances of \hat{\mathrm{H}}... — Mico, Jun 14 '18 at 08:25
No, it is not, the H is not a matrix nor a vector just a constant. — user3671704, Jun 14 '18 at 11:16
