    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。 Z`0r]V`Ys  
    Huug_E+  
    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: =B ,_d0Id  
    enableservice('AutomationServer', true) q_%w l5\F  
    enableservice('AutomationServer') W? 6  
    :c+a-Py $E  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 oK(W)[u  
    .wt>.mUH  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: w2M IY_N?  
    1. 在FRED脚本编辑界面找到参考. ps{&WT3a  
    2. 找到Matlab Automation Server Type Library ?$`1%Y9  
    3. 将名字改为MLAPP 7oqn;6<[>,

    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。 A+bu bH,

    1. 创建Matlab服务器。 =":V WHf  
    2. 移动探测面对于前一聚焦面的位置。 OA8b_k~  
    3. 在探测面追迹光线 ^0 ,&R\e+  
    4. 在探测面计算照度 ;]O 7^s#v  
    5. 使用PutWorkspaceData发送照度数据到Matlab !]jNVg  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 j_YZ(: =  
    7. 用Matlab画出照度数据 DlQ[}5STF

    9. 返回数据到FRED中 Ow&'sR'CX
