    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。 p-1 3H0Kt  
    gTA%uRBa  
    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: DjSbyXvrg  
    enableservice('AutomationServer', true) P!"&%d  
    enableservice('AutomationServer') OKF tl  
    +cD!1IT:  
    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 j"AU z)x  
    J|&JD?  
    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: dt2$`X18  
    1. 在FRED脚本编辑界面找到参考. Vp>|hj po  
    2. 找到Matlab Automation Server Type Library x\Z'2?u}  
    3. 将名字改为MLAPP (' -JY  
    V+I|1{@i0  
    `7/Y@}n  
    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。 2h[85\4

    现在将脚本代码公布如下,此脚本执行如下几个步骤: rj6#1kt  
    1. 创建Matlab服务器。 oh$Q6G  
    2. 移动探测面对于前一聚焦面的位置。 ew"v{=X  
    3. 在探测面追迹光线 =m5SK5vLKT  
    4. 在探测面计算照度 vDH>H^9Y  
    5. 使用PutWorkspaceData发送照度数据到Matlab X/N0LU(q  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 X^WrccNX  
    7. 用Matlab画出照度数据 ~ o1x;Y6  
    8. 在Matlab计算照度平均值 x' .:&z  
    9. 返回数据到FRED中 Qx[t /~
