    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。 Q]q`+ Z65  
    QQ5G?E  
    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: ;c-J)Ky  
    enableservice('AutomationServer', true) ];.H]TIc6  
        enableservice('AutomationServer') +s}"&IV%  
    Q9`}dYf.  
    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 St6U

    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: h7( R/Rf  
    1. 在FRED脚本编辑界面找到参考. F .(zS(q  
    2. 找到Matlab Automation Server Type Library XkWO-L  
        3. 将名字改为MLAPP O+Zt*jN;

         J1?)z+t9~  
    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。 Ig hd,G-

    1. 创建Matlab服务器。 `|1#Vuk  
    2. 移动探测面对于前一聚焦面的位置。 D=w5Lks  
    3. 在探测面追迹光线 Q.q'pJ-  
    4. 在探测面计算照度 Hq{i-z+  
    5. 使用PutWorkspaceData发送照度数据到Matlab ? (&)p~o  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 wz-#kH5?  
    7. 用Matlab画出照度数据 ,<[Q/:}[
