    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。 2mO#vTX4  
    JA}'d7yEa  
    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: hK"=~\,  
    enableservice('AutomationServer', true) jysV%q 3  
    enableservice('AutomationServer') [0LqZ<\5  
    aC},h   
    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 h=tu +pn  
    c-T ^ aR  
    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: AN>`M?EQ  
    1. 在FRED脚本编辑界面找到参考. P~<93  
    2. 找到Matlab Automation Server Type Library CJOl|"UyJ  
    3. 将名字改为MLAPP ##_Za6/n  
    StL[\9~:  
    ) T1 oDk  
    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。 *\WI!%

    现在将脚本代码公布如下,此脚本执行如下几个步骤: "k|`xn  
    1. 创建Matlab服务器。 h6e$$-_  
    2. 移动探测面对于前一聚焦面的位置。 $te,\$&}  
    3. 在探测面追迹光线 EAB+kY  
    4. 在探测面计算照度 lnWi E}F  
    5. 使用PutWorkspaceData发送照度数据到Matlab F"H!CJJu&  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 w2+]C&B*  
    7. 用Matlab画出照度数据 aTm.10{^  
    8. 在Matlab计算照度平均值 j*u9+.   
    9. 返回数据到FRED中 W~F/ZrT3A
