    简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 owKOH{otf  
    X|Rw;FY  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: Dg'BlrwbR  
    enableservice('AutomationServer', true) Xn # v!  
        enableservice('AutomationServer') 45U!\mG  
    (Y:?qy  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 ~tB#Q6`nB  
    hzV= 7  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: qi=v}bp&  
    1. 在FRED脚本编辑界面找到参考. o3,}X@p  
    2. 找到Matlab Automation Server Type Library =)IV^6~b  
        3. 将名字改为MLAPP H-/w8_} KG  
         MNu\=p\Eq  
         nk.j7tu  
    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。  @s7wKk

    现在将脚本代码公布如下,此脚本执行如下几个步骤: b<8,'QgB  
    1. 创建Matlab服务器。 v18OUPPX  
    2. 移动探测面对于前一聚焦面的位置。 vTq [Xe"  
    3. 在探测面追迹光线 &at>sQ'  
    4. 在探测面计算照度 4H_QQ6  
    5. 使用PutWorkspaceData发送照度数据到Matlab yP0XA=,Y  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 'h3yxf}\  
    7. 用Matlab画出照度数据 -n~%v0D8c  
    8. 在Matlab计算照度平均值 :]uz0s`>  
    9. 返回数据到FRED中 :)DvZxHE@
