    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。 #oW" 3L{,  
    -Aaim`06bv  
    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: <hvs{}TS  
    enableservice('AutomationServer', true) k<Qhw)M8  
        enableservice('AutomationServer') 1o`zAJ8|2  
    ' Dcj\=8  
    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 x{4{.s%+:  
    SO4?3wg7  
    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: 6I2` oag  
    1. 在FRED脚本编辑界面找到参考. ^F,sV*  
    2. 找到Matlab Automation Server Type Library _t&` T  
        3. 将名字改为MLAPP /o OZ>B%1s  
         ORuC("  
         /s*.:cdH  
    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。 z36wWdRa6

    1. 创建Matlab服务器。 P q0 %oz  
    2. 移动探测面对于前一聚焦面的位置。 @,Z0u2WLl6  
    3. 在探测面追迹光线 .DNPL5[v  
    4. 在探测面计算照度 7UIf   
    5. 使用PutWorkspaceData发送照度数据到Matlab Ps!umV  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 $vrkxn  
    7. 用Matlab画出照度数据 5skxixG  
    8. 在Matlab计算照度平均值 0vETg'r  
    9. 返回数据到FRED中 3xg9D.A
