    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。 5HqvSfq>?  
    z?I"[M  
    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: \)'5V!B|s  
    enableservice('AutomationServer', true) bK69Rb@\A  
    enableservice('AutomationServer') e\7AtlW"  
    m*f"Y"B.1I  
    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 s'4%ZE2Dr

    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: b2 5.CGF  
    1. 在FRED脚本编辑界面找到参考. RoLN#  
    2. 找到Matlab Automation Server Type Library h%UM<TZ]"  
    3. 将名字改为MLAPP L4t( Y7  
    xMr=tU1C  
    %5yP^BL0  
    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"

    现在将脚本代码公布如下,此脚本执行如下几个步骤: ]]^r)&pox  
    1. 创建Matlab服务器。 $No^\.mV  
    2. 移动探测面对于前一聚焦面的位置。 mTU[khEmL=  
    3. 在探测面追迹光线 \`oP\|Z  
    4. 在探测面计算照度 \TS.9 >\  
    5. 使用PutWorkspaceData发送照度数据到Matlab 3\2^LILLO  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 Y~Z&h?H'}  
    7. 用Matlab画出照度数据 Min {&?a  
    8. 在Matlab计算照度平均值 'Y22HVUX  
    9. 返回数据到FRED中 ' TO/i:{\
