    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。 !F&Ss|(}  
    d;10[8:5=  
    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: ,| EaW& 2  
    enableservice('AutomationServer', true) #=B~} _  
        enableservice('AutomationServer') j4G?=oDb  
    /*8Ms`  
    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 w;p!~o &  
    m!-,K8  
    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: s&7,gWy}BE  
    1. 在FRED脚本编辑界面找到参考. 7VQk$im399  
    2. 找到Matlab Automation Server Type Library ;0f?-W?1  
        3. 将名字改为MLAPP gM<*(=x'  
         /"M7YPX;  
         Gf{FFIe(  
    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。 s!d"(K9E

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ;w_f^R #  
    1. 创建Matlab服务器。 IT u6m<V  
    2. 移动探测面对于前一聚焦面的位置。 K;wd2/jmJ  
    3. 在探测面追迹光线 )Ekp <2B:0  
    4. 在探测面计算照度 ,\BGxGNAmV  
    5. 使用PutWorkspaceData发送照度数据到Matlab i YJzSVO  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 .l->O-=  
    7. 用Matlab画出照度数据 {)QSxO  
    8. 在Matlab计算照度平均值 i$A0_ZJKjZ  
    9. 返回数据到FRED中 dm&vLQVS
