    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。 sa'1hX^@  
    NsB]f{7>8+  
    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: k!Yc_ZB:*l  
    enableservice('AutomationServer', true) FOF@@C~aH  
    enableservice('AutomationServer') 72, m c  
    C~2!@<y  
    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 SA<\n+>q^  
    h%EeU 3  
    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: ?F05BS#)X  
    1. 在FRED脚本编辑界面找到参考. 1ui)Hv=h*  
    2. 找到Matlab Automation Server Type Library }PI:O%N;  
    3. 将名字改为MLAPP h7#\]2U$[5  
    H_?rbz}o  
    nI3p`N8j*  
    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。 GlJ[rD

    现在将脚本代码公布如下,此脚本执行如下几个步骤: pB:XNkxL  
    1. 创建Matlab服务器。 T f3CyH!k  
    2. 移动探测面对于前一聚焦面的位置。 9Jwd*gevV  
    3. 在探测面追迹光线 3H,x4L5j  
    4. 在探测面计算照度 Bc8&-eZ ,  
    5. 使用PutWorkspaceData发送照度数据到Matlab 5|rBb[  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 5len} ){  
    7. 用Matlab画出照度数据 d`/8Q9tQ  
    8. 在Matlab计算照度平均值 t oA}0MI(:  
    9. 返回数据到FRED中 FxlH;'+Q
