Linear Algebra 11q: Algorithm for Calculating the Inverse Matrix

[prateekamrawanshi]

Its amazing that while repeating the algorithm you played soccer video in the the left bottom, so funny and out of box idea

2:24 You're using the Messi Algorithm for matrix inversion then?

I like how you've taken a 'standard' non-invertible matrix (in the 'keypad) and simply tweaked one of it's values. Is it the case that any singular matrix can be 'perturbed' into becoming a slightly different but invertible one? That makes non invertible matrices somehow 'special' in the space of all matrices does it not? (like how your 3 -drumsticks- geometrical vectors practically never fall into planar aligment when tossed)

I saw an algorithm without the augmentation of identity matrix which is good if we want to save some space
I found Pascal source code for calculating inverse matrix in textbook written in Polish language
I translated code to C
(include conio.h line can be deleted)
I calculated the inverse matrix following the istructions of this code but ...
Could you explain this method
In Knuth's book "The Art of computer programming" is presented another algorithm
