    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。 Kat&U19YH  
    f.6~x$:)`E  
    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: gl7|H&&xV  
    enableservice('AutomationServer', true) Y)|N"f;  
    enableservice('AutomationServer') 27A!\pn  
    m3.sVI0I  
    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 p2 %  
    u:dx;*  
    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: 9 OT,TpA  
    1. 在FRED脚本编辑界面找到参考. GP a`e  
    2. 找到Matlab Automation Server Type Library /*rhtrS)  
    3. 将名字改为MLAPP u2iXJmM*  
    V/%~F6e  
    Z(GfK0vU  
    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。 RU#F8O

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 1AD]v<M  
    1. 创建Matlab服务器。 W+=o&V  
    2. 移动探测面对于前一聚焦面的位置。 p $`92Be/  
    3. 在探测面追迹光线 I)SG wt-  
    4. 在探测面计算照度 *rh,"Zo  
    5. 使用PutWorkspaceData发送照度数据到Matlab }q[Bd  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 O7G"sT1Dv  
    7. 用Matlab画出照度数据 5:.{oSy7n  
    8. 在Matlab计算照度平均值 >I"V],d!6  
    9. 返回数据到FRED中 u bW]-U=T
