Functions
cond
Constructs conditional expression (similar to Lisp's cond). cond(cond_1, expr_1, cond_2, expr_2, ..., ..., cond_n, expr_n, expr_{n+1}) The value returned by the above cond expression is expr_1 if cond_1 is true; else if cond_2 is true then expr_2; ... ; else if cond_n is true then expr_n. If none of the conditions are true, it returns expr_{n+1}. Note This functions assumes that ScalarType provides operator< and the type of f_cond is the type of the return type of operator<(ScalarType, ScalarType). For example, symbolic::Expression can be used as a ScalarType because it provides symbolic::Formula operator<(symbolic::Expression, symbolic::Expression).
