    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。 x[GFX8h(k6  
    @!L@UP0  
    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: dK0}% ]i3#  
    enableservice('AutomationServer', true) eeI9[lTw  
        enableservice('AutomationServer') %KabyvOl)  
    )H[h53bIq  
    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 HobGl0<y

    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: <eud#v  
    1. 在FRED脚本编辑界面找到参考. BRo R"#'  
    2. 找到Matlab Automation Server Type Library V',m $   
        3. 将名字改为MLAPP 4 BE:&A  
         {Gk}3u/  
         8^P2GG'+-  
    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。 ;*>QG6Fh

    现在将脚本代码公布如下,此脚本执行如下几个步骤: +s+PnZ%0V  
    1. 创建Matlab服务器。 OVQxZ~uQ  
    2. 移动探测面对于前一聚焦面的位置。 9AVK_   
    3. 在探测面追迹光线 m 1'&{O:  
    4. 在探测面计算照度 cjy0s+>>  
    5. 使用PutWorkspaceData发送照度数据到Matlab ${TB2q}%  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 5fvUv"m  
    7. 用Matlab画出照度数据 ;4S [ba1/  
    8. 在Matlab计算照度平均值 :uT fhr  
    9. 返回数据到FRED中 DMK"Q#Vw
