    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。 NqWHR~&  
    pFK |4u  
    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: Z 0:2x(x9  
    enableservice('AutomationServer', true) lfA  BF  
        enableservice('AutomationServer') 8iCI s=06  
    !69^ kIi$  
    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 `~RV  
    2 9]8[Z,4  
    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: 9t[278B6  
    1. 在FRED脚本编辑界面找到参考. N!v@!z9Mu  
    2. 找到Matlab Automation Server Type Library }.'%gJrS  
        3. 将名字改为MLAPP 1Q%.-vs

    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。 EH:1Z*|Z{\

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ~ /[Cgh0  
    1. 创建Matlab服务器。 mx[^LaR>v  
    2. 移动探测面对于前一聚焦面的位置。 So^`L s;S  
    3. 在探测面追迹光线 +E:(-$"R  
    4. 在探测面计算照度 oL@ou{iQ  
    5. 使用PutWorkspaceData发送照度数据到Matlab >(CoXSV5  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 S3'g(+S  
    7. 用Matlab画出照度数据 Fs|;>Up0  
    8. 在Matlab计算照度平均值 E oR(/*'  
    9. 返回数据到FRED中 'k67$H
