    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。 Ry S{@=si  
    ^r :A^q  
    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: }<h. chz,  
    enableservice('AutomationServer', true) 49fq6ZhO  
        enableservice('AutomationServer') 8 (h  
    ViT 5Jn7  
    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 {bW3%iU  
    <a[8;YQC  
    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: M>gZVB,eP>  
    1. 在FRED脚本编辑界面找到参考. b{>dOI*.}  
    2. 找到Matlab Automation Server Type Library y/6LMAI  
        3. 将名字改为MLAPP A y[L{!)2{  
         T|2%b*/  
         _:p_#3s$  
    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。 j4r,_lH^r

    现在将脚本代码公布如下,此脚本执行如下几个步骤: !D&MJThNy  
    1. 创建Matlab服务器。 c+/C7C o  
    2. 移动探测面对于前一聚焦面的位置。 YY~=h5$  
    3. 在探测面追迹光线 j:KQIwc  
    4. 在探测面计算照度 rg/vxTl  
    5. 使用PutWorkspaceData发送照度数据到Matlab Y(Ezw !a  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 Y mjS!H  
    7. 用Matlab画出照度数据 :=eUNH  
    8. 在Matlab计算照度平均值 J\D3fh97-  
    9. 返回数据到FRED中 2B dr#qr
