• =EVAL(head, arg1, arg2, ...) is equivalent to =EVAL(EXPR(head, arg1, arg2, ...)). • You can use =EXPR(head, arg1, arg2, ...) to see exactly what will be evaluated in Mathematica. • =EVAL(head, arg1, arg2, ...) evaluates only once head and all arguments have been provided. If head or any argument refers to an empty cell or an error, evaluation is suppressed and #N/A is returned. |
