    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。 %D:5 S?{  
    _ Oe|ZQ  
    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: ofA6EmQ37  
    enableservice('AutomationServer', true) ds9`AiCW>  
    enableservice('AutomationServer') k&>l#oH  
    kg_f;uk+  
    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 `[J(a u$z  
    % 1p4K)  
    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: ,Uv8[ci%9  
    1. 在FRED脚本编辑界面找到参考. y Yvv;E  
    2. 找到Matlab Automation Server Type Library ,.+"10=N.  
    3. 将名字改为MLAPP wOp# mT

    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。 A*:(%!

    现在将脚本代码公布如下,此脚本执行如下几个步骤: K{00 V#  
    1. 创建Matlab服务器。 i#~1|2  
    2. 移动探测面对于前一聚焦面的位置。 -=]LQHuQ  
    3. 在探测面追迹光线 7TQh'j   
    4. 在探测面计算照度 (dC<N3  
    5. 使用PutWorkspaceData发送照度数据到Matlab It\o b7n  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 |KFWW  
    7. 用Matlab画出照度数据 )>LC*_v  
    8. 在Matlab计算照度平均值 `|^<y.-6  
    9. 返回数据到FRED中 _u:4y4}
