In the process of being built - use at your own risk.

Running ./run.sh will compile the code and run the top-level driver file I am using for testing.

• Initialize a matrix from
  • two-dimensional arrays
  • one-dimensional arrays
  • strings**
  • files**
• Unary matrix operations
  • abs
  • negative
  • transpose
• Binary matrix operations
  • addition
  • subtraction
  • scalar multiplication
  • matrix multiplication
  • concatenation
• Other
  • trace
  • determinant
  • minor
  • inverse
  • reduction to echelon form and reduced row echelon form
  • rank
• Boolean
  • echelon form
  • reduced row echelon form
  • invertible
  • full rank
  • linearly dependent / independent
• Potentially also
  • fill with random values
  • shuffle**
  • resize**
  • sparse matrices with sparsify/densify functions**
  • flexible numerical types
  • smart slicing

** not yet implemented

• All about Java exceptions (checked and unchecked)
• Wrote my first custom exception (then deleted it because I found better pre-existing ones)
• Bundling Java classes++ into a package / accessing package members
• MATH!
• Realized that Java generics are somewhat restrictive - since I needed my underlying matrix representation to have a 2D array of double values, I had to duplicate a lot of code to allow flexibility at the user end in instantiating matrices with int or float array values
• Practised good documentation + used javadocs for the first time
• Dealt with agonizing errors from lossy floating-point arithmetic - thinking about a fix for this
