    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。 K$z2YJ%  
    lPe&h]@ >  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: eYc$ dPE  
    enableservice('AutomationServer', true) k x8G  
    enableservice('AutomationServer') ^23~ZHu  
    b;L\EB  
    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 mupT<_Y

    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: s `e{}\  
    1. 在FRED脚本编辑界面找到参考. }czrj%6  
    2. 找到Matlab Automation Server Type Library ~ \r*  
    3. 将名字改为MLAPP  C;v.S5x

    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。 AI2~Jp

    1. 创建Matlab服务器。 g%o(+d  
    2. 移动探测面对于前一聚焦面的位置。 mb 1FWy=3  
    3. 在探测面追迹光线 >k|5Okq g  
    4. 在探测面计算照度 )',R[|<  
    5. 使用PutWorkspaceData发送照度数据到Matlab 'z8pzMmT  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 +8T?{K  
    7. 用Matlab画出照度数据 pR<`H'  
    8. 在Matlab计算照度平均值 cF*TotU_m  
    9. 返回数据到FRED中 `Uq#W+r,
