    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。 dU6ou'p f  
    aH 4c02s$  
    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: vL|SY_:4  
    enableservice('AutomationServer', true) Of- Rx/  
        enableservice('AutomationServer') bt"W(m&f  
    B:dB,3,`(  
    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 9*2[B"5  
    H;?{BV  
    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: {v=T [D  
    1. 在FRED脚本编辑界面找到参考. gcE|#1>  
    2. 找到Matlab Automation Server Type Library {E p0TVj`  
        3. 将名字改为MLAPP NgADKrDU  
         ~rlB'8j(  
         t0/p]=+.p/  
    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。 {\S+#W\

    现在将脚本代码公布如下,此脚本执行如下几个步骤: lphFhxJA{  
    1. 创建Matlab服务器。 3[\iQ*d }B  
    2. 移动探测面对于前一聚焦面的位置。 Ky|88~}:C9  
    3. 在探测面追迹光线 ZRv*!n(Ug<  
    4. 在探测面计算照度 u6M.'  
    5. 使用PutWorkspaceData发送照度数据到Matlab o 4`hY/<t  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 ,oN8HpGs  
    7. 用Matlab画出照度数据 FYOD Upn  
    8. 在Matlab计算照度平均值 N96jJk  
    9. 返回数据到FRED中 !,l9@eJQ
