    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。 9 Vq   
    rAtCG1Vr  
    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: ;bG?R0a  
    enableservice('AutomationServer', true) XK\nOHLS  
        enableservice('AutomationServer') 3| w$gG;Y  
    wz3X;1l`c  
    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 Uu8ayN j  
    o|d:rp!^  
    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: /-!Fr:Ox>  
    1. 在FRED脚本编辑界面找到参考. xGr{ad.N  
    2. 找到Matlab Automation Server Type Library yw:%)b{  
        3. 将名字改为MLAPP u9Adu`  
         VF11eZ"  
         ;]xc}4@=mg  
    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。 ]:@{tX 7c

    1. 创建Matlab服务器。 *YH!L{y  
    2. 移动探测面对于前一聚焦面的位置。 HOu$14g  
    3. 在探测面追迹光线 g&$5!ifgi  
    4. 在探测面计算照度 H0tu3Pqk  
    5. 使用PutWorkspaceData发送照度数据到Matlab !21G $ [H  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 72RTEGy  
    7. 用Matlab画出照度数据 a0]GQyIG  
    8. 在Matlab计算照度平均值 L"vk ^>E6
