SymbolMath

SymbolMath is a small symbolic math experiment using Ruby 2.0+

Examples

expression = SymbolMath::expr { a**2 + b**2 }
expression.fdiff(:a) # => (2 * <Symbol: a>)
expression.evaluate(a: 2, b: 5) # => 29

expression = SymbolMath::expr { sin(x) }
expression.taylor(:x, 5).to_s # => "((x / 1!) + (-(x ** 3) / 3!) + ((x ** 5) / 5!))"
