MatRepl

• is a Matrix
• and a repl: Read–Eval–Print Loop, where Print is doing operations on vectors and matrices in a graphic environment

The repl has the following syntax (It's work in progress, new capabilities will be added)

• simple arithmetic expressions: ** add, subtract, divide, multiply ** variable declaration eg: a= ... ** vector(x0,y0,x,y) adds a vector ** remove(x) removes bindings (when it's an object (eg vector), removes it from the matrix) ** method calls: *** a = vector(0,0,12,1) *** a.type() *** > vector ** property lookup *** a.x *** 12
