    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。 o8<~zeI  
    [:gg3Qzx  
    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: u*I'c2m  
    enableservice('AutomationServer', true) D]*|Zmr+}  
        enableservice('AutomationServer') bQq/~  
    $.d,>F6  
    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 n&P~<2^M#  
    R6fkc^  
    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: o/V T"cT  
    1. 在FRED脚本编辑界面找到参考. ,vf#e= Z  
    2. 找到Matlab Automation Server Type Library Op]*wwI*h  
        3. 将名字改为MLAPP P;z\vq<h  
         nr -< mQ  
         6.KEe^[-  
    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。 ]ilLed

    现在将脚本代码公布如下,此脚本执行如下几个步骤: NNqvjM-  
    1. 创建Matlab服务器。 XL aD#J  
    2. 移动探测面对于前一聚焦面的位置。 d^6-P  R_  
    3. 在探测面追迹光线 V-go?b`  
    4. 在探测面计算照度 "p;tj74O9  
    5. 使用PutWorkspaceData发送照度数据到Matlab lGR0-Gh2  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 %(khE-SW  
    7. 用Matlab画出照度数据 )LKJfoo PY  
    8. 在Matlab计算照度平均值 2 G*uv+=  
    9. 返回数据到FRED中 d ([~o
