    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。 G<Urj+3/Xo  
    C|]Zpn#{K  
    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: 6t gq.XL^n  
    enableservice('AutomationServer', true) F(w<YU %6  
        enableservice('AutomationServer') cL4Xh|NBp  
    *r ('A  
    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 SVPksr  
    j{@li1W@  
    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: 1";s #Jq  
    1. 在FRED脚本编辑界面找到参考. ES)_X:\X?V  
    2. 找到Matlab Automation Server Type Library K{XE|g  
        3. 将名字改为MLAPP  WfQZ7e

    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。 +9M";'\c

    1. 创建Matlab服务器。 .-1'#Z1T  
    2. 移动探测面对于前一聚焦面的位置。 Gsy'':u  
    3. 在探测面追迹光线 c=re(  
    4. 在探测面计算照度 lInf,Q7W  
    5. 使用PutWorkspaceData发送照度数据到Matlab 9 $^b^It  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 NKiWt Z"  
    7. 用Matlab画出照度数据 I")mg~f
