May I request you to let me know the steps python follows in order to
compute covariance matrix using the inbuilt
syntax.
np.cov(cov_mat) .

1. When starting a new topic, start a new thread with a new topic.
2. Questions about the internals of a 3r

Thanks, the problem was I solved a covariance matrix manually, but my
fellow mate using the covariance syntax. That's why there was difference in
Matlab and python results. But now when I use the covariance syntax in
python, matlab and python gives the same results.

Decimal doesn't avoid floating point problems, because it is a floating
point format. For example:

[GCC 9.3.0] on linux

When I use the same code in MATLAB I get the answer as 4.6e-06 and when I
use the same code in PYTHON I get the answer as 4.7e-06. How do I know
which is the most precise and accurate value. Actually the answer is a big
matrix, I've only compared the first entry of the matrix.

If you want to avoid float problems, you can use Decimal:

How is PYTHON better than other software's(MATLAB) in case of truncation or
rounding off error.
Thanks
