    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。 "~ $i#  
    S g1[p#U  
    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: =gJ{75tV3  
    enableservice('AutomationServer', true) w8Z#]kRv  
    enableservice('AutomationServer') XPMUhozV  
    pA_u;*  
    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 #\Y`?  
    |3B<;/v5  
    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: hLZf A rq}  
    1. 在FRED脚本编辑界面找到参考. ^1F zs(#.  
    2. 找到Matlab Automation Server Type Library 'R-\6;3E>9  
    3. 将名字改为MLAPP +kYp!00

    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。 [efU)O&

    现在将脚本代码公布如下,此脚本执行如下几个步骤: )=K8mt0qob  
    1. 创建Matlab服务器。 Myg;2.  
    2. 移动探测面对于前一聚焦面的位置。 Q) aZ0 Pt  
    3. 在探测面追迹光线 _)= e`9%  
    4. 在探测面计算照度 &XcPHZy'  
    5. 使用PutWorkspaceData发送照度数据到Matlab Qu'#~#L`  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 kBC$dW-  
    7. 用Matlab画出照度数据 l\AdL$$Mb  
    8. 在Matlab计算照度平均值 2Ul8<${c{  
    9. 返回数据到FRED中 ,GVX1B?
