    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。 H8(0. IR  
    Vu_7uSp,)  
    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: ^K1~eb*K  
    enableservice('AutomationServer', true) +H2m<  
    enableservice('AutomationServer') g] 7{ 5  
    vWPM:1A  
    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 \}]=?}(

    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: y\r^\ S9%  
    1. 在FRED脚本编辑界面找到参考. U]`'GM/x  
    2. 找到Matlab Automation Server Type Library Cy`<^_i  
    3. 将名字改为MLAPP s0X/1Cq

    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。  :V5!C$QV

    现在将脚本代码公布如下,此脚本执行如下几个步骤: {y+v-v/#  
    1. 创建Matlab服务器。 2yi*eR  
    2. 移动探测面对于前一聚焦面的位置。 2ZTyo7P  
    3. 在探测面追迹光线 L XTipWKz  
    4. 在探测面计算照度 b7>-aem@I  
    5. 使用PutWorkspaceData发送照度数据到Matlab YKs^%GO+  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 n##w[7B*  
    7. 用Matlab画出照度数据 ?h>%Ix  
    8. 在Matlab计算照度平均值 nkr,  
    9. 返回数据到FRED中 0s+rd&
