    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。 QlCs ,bT  
    sV`!4 u7%}  
    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: ^>ICycJ  
    enableservice('AutomationServer', true) {WoS&eL  
    enableservice('AutomationServer') qlgo#[i  
    \DC0`  
    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 yhSbX4Q  
    lqoJ2JMy  
    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: TtKV5  
    1. 在FRED脚本编辑界面找到参考. FLzC kzJ:6  
    2. 找到Matlab Automation Server Type Library # %$U-ti  
    3. 将名字改为MLAPP n3Q Rn^  
    nA?Ks!9T  
    nWz7$O  
    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。 $]t3pAI[H0

    现在将脚本代码公布如下,此脚本执行如下几个步骤: J70r`   
    1. 创建Matlab服务器。 o3OtG#g2  
    2. 移动探测面对于前一聚焦面的位置。 X&14;lu%p  
    3. 在探测面追迹光线 'NYW`,  
    4. 在探测面计算照度 #l?E2 U4WL  
    5. 使用PutWorkspaceData发送照度数据到Matlab #Li6RSeW  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 R Q2DTQ-$  
    7. 用Matlab画出照度数据 ]oIP;J:&  
    8. 在Matlab计算照度平均值 me@xl }  
    9. 返回数据到FRED中 xg8$ <Ut
