tool: D80: 
Usage: LinAlg [ROWS] [COLS] [BUFFER]
NOTE: 3rd argument is optional floating point percision setting.


tool: D83: 
This main serves a short testing file.
An example of the library is shown here.

Our Original Matrix. Here we will call it A:

tool: D126: 

Using ref(), this is a Row Echelon Form of A.

tool: D10: 

And this is its determinant %+2.4f according to ref().

tool: D118: 

This is the inverse of A:

tool: D54: 

Its determinant is as calculated by invert() is %+2.4f.

tool: D138: 

This is the Product of A and its inverse:

tool: D122:  %+2.4f 

tool: D82: 

You did it, Hooray!
