    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。 AB.gVw| 4  
    {hXIP`  
    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: tfSY(cXg'T  
    enableservice('AutomationServer', true) T;4& ^5 n  
    enableservice('AutomationServer') Nx%]dOa  
    &V.\Svm8]  
    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 $RFy9(>  
    <;O -N=  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: fku\O<1  
    1. 在FRED脚本编辑界面找到参考. o!\Q,  
    2. 找到Matlab Automation Server Type Library 9L`5r$/  
    3. 将名字改为MLAPP ^-*q

    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。 Ew&pwsQ

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 0`LR!X  
    1. 创建Matlab服务器。 8RA]h?$$J  
    2. 移动探测面对于前一聚焦面的位置。 vxey $Ir  
    3. 在探测面追迹光线 n!Ic.T3PA  
    4. 在探测面计算照度 yFD3:;}  
    5. 使用PutWorkspaceData发送照度数据到Matlab ^PNE6  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 .nN>Ipv  
    7. 用Matlab画出照度数据 d4 Hpe>  
    8. 在Matlab计算照度平均值  1\[En/6  
    9. 返回数据到FRED中 lj U|9|v
