    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。 Ay0.D FL  
    I8f='  
    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: |B {*so]  
    enableservice('AutomationServer', true) weH3\@  
    enableservice('AutomationServer') IictX"3lh  
    l5/gM[0_7  
    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 JbAmud,  
    m "96%sB  
    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: IU;a$  
    1. 在FRED脚本编辑界面找到参考. FfNUFx2N  
    2. 找到Matlab Automation Server Type Library ^^B~v<uK  
    3. 将名字改为MLAPP m5v IS

    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。 )4TP{tp

    1. 创建Matlab服务器。 [ 2PPa9F  
    2. 移动探测面对于前一聚焦面的位置。 K /$-H#;N  
    3. 在探测面追迹光线 55FRPNx-x  
    4. 在探测面计算照度 SBI *[  
    5. 使用PutWorkspaceData发送照度数据到Matlab J7Mbv2D  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 zpjE_|  
    7. 用Matlab画出照度数据 OT0IGsJ"'  
    8. 在Matlab计算照度平均值 >a&IFi,j
