    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。 4a~9?}V:  
    {GH 0 J"  
    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: I1(, J  
    enableservice('AutomationServer', true) ZjJEjw  
    enableservice('AutomationServer') `qsn;  
    -r82'3]  
    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 U `"nX)$  
    A d7=JzV  
    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:  HPj7i;?O  
    1. 在FRED脚本编辑界面找到参考. V# 6`PD6  
    2. 找到Matlab Automation Server Type Library =l3* { ?G  
    3. 将名字改为MLAPP W,>;`>  
    h^0!I TL^  
    R\=y/tw0H  
    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。 {/ _.]Vh

    1. 创建Matlab服务器。 ODM<$Yo:d  
    2. 移动探测面对于前一聚焦面的位置。 'bg%9}  
    3. 在探测面追迹光线 Hp":r%)  
    4. 在探测面计算照度 !NYc!gYD  
    5. 使用PutWorkspaceData发送照度数据到Matlab S*CRVs  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 aARm nV  
    7. 用Matlab画出照度数据 XH2g:$  
    8. 在Matlab计算照度平均值 HWGlC <  
    9. 返回数据到FRED中 ? B^*YCo7(
