4、t types will be self-explanatory, e. g. E and H fields being phasor quantities will be Complex Vector (CVc). The only exception to this rule is the Poynting input, Which will show up as a “CVc” even though E X H* should have no imaginary component. The calculator only knows that two complex vector w

5、ere crossed, and does not know ahead of time that the imaginary component has been zeroed. 第25页/共48页 As data is entered into the calculator it appears at the TOP of the stack, pushing older entries DOWN UNDO attempts to take back the last operation between stack enties. It may not work for all data

6、types (e.g. the result of a pure math operation cannot be reversed) CLEAR deletes ALL entries from the stack upon confirmation EXCH exchanges or swaps the top two stack entries PUSH duplicates the top stack entry POP deletes the top entry off the stack RLDN “rolls” the stack downward, moving the top

VECTOR column contains operations to be performed on vector data such as converting to scalar, Dot and Cross products,and Unit Vector computations GENERAL column contains operations

9、which can be performed on many data types (e. g. adding scalar values or adding vectors) INPUT column contain all operations which input new data into the stack (field data, constant, user-entered vector or complex numbers, etc. All calculator operations are orgnized into columns classifyying them b

To see the steps that went in

11、to the generating the plot you just created, open the calculator interface and view the stack contents. This can often help guide you as you try to use the calculator to created your own custom outputs. 第29页/共48页 Always think of what type of data you are working with and whether or not it is compati
