    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。 /XhIx\40 l  
    _g~qu [1  
    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: [L:o`j  
    enableservice('AutomationServer', true) h\PHK C2  
    enableservice('AutomationServer') >]W)'lnO  
    ?84 s4BpV1  
    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 Kwg4sr5"D  
    s;64N'HH  
    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: Z| V`B `  
    1. 在FRED脚本编辑界面找到参考. QoG cWJ  
    2. 找到Matlab Automation Server Type Library `kU/NKq  
    3. 将名字改为MLAPP U5He?

    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。 #3_*]8K.R

    现在将脚本代码公布如下,此脚本执行如下几个步骤: qt;y2gf=  
    1. 创建Matlab服务器。 tPGJ<30  
    2. 移动探测面对于前一聚焦面的位置。 l"2OP6d  
    3. 在探测面追迹光线 %"af748!+D  
    4. 在探测面计算照度 82]vkU  
    5. 使用PutWorkspaceData发送照度数据到Matlab opJMS6%r  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 k31I ysh  
    7. 用Matlab画出照度数据 A _XhuQB;d  
    8. 在Matlab计算照度平均值 kjtjw1\o  
    9. 返回数据到FRED中 rORZerM
