Needed a specifically formatted table with some bold lines and some lines without bold face. Did the bold lines as per

That is,
"Under Table Tools/Design menu, go to Draw Borders and adjust the line values to your preference. Then click on Draw Table and a pencil icon will appear. Click on any line and voila! The line is now set to your liking."

speed comparison - Matlab vs C vs python vs perl

I had found C code to be around 150x faster than Matlab for my implementation of the Monte Carlo code in Matlab.

User time:        3 sec for the C program
elapsed_time =  453.2500 sec  for the Matlab program

This stackoverfloe discussion has some interesting points to make - use Matlab first to get correct results, then increase speed with C, beware of errors in C libraries.

These benchmarks show python to be 3x to 100x slower than C - so, translating from Matlab to python in search of speed gains may not make sense.

These benchmarks show perl having similar speeds as python for loops - so I needn't explore perl, either.

miui permissions

On the Xiaomi Mi3 phone which runs the MIUI skin for Android, the method for setting permissions for apps is slightly different from the method for stock Android phones. The method for MIUI is via the Security App on the home screen, Security -> Permissions -> Permissions -> (Choose the type of permission like Contacts etc) -> enable or disable per app.

This is for MIUI Global 7.5, running on Android 6.0.1
