    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。 (#dwIBBFt  
    cWd\Ki  
    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: MQ9Nn|4  
    enableservice('AutomationServer', true) 9rB,7%@EL  
    enableservice('AutomationServer') +x7b9sHJ  
    Z# +{ksU  
    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 S690Y]:h$v  
    @+gr>a1K#  
    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: aaN|g{pX  
    1. 在FRED脚本编辑界面找到参考. /``4!jU  
    2. 找到Matlab Automation Server Type Library ^x! N]  
    3. 将名字改为MLAPP 4oY<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。 !N`$`qAK

    3. 在探测面追迹光线 %s+H& vfQs  
    4. 在探测面计算照度 igoXMsifT+  
    5. 使用PutWorkspaceData发送照度数据到Matlab Ya#,\;dTT  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 MH"{N "|  
    7. 用Matlab画出照度数据 ?r~|B/ ]  
    8. 在Matlab计算照度平均值 {^r8uKo:~
