    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。 +Hy4s[_|  
    +rQg7a}  
    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: x*mc -&N  
    enableservice('AutomationServer', true) #1l7FT?q  
    enableservice('AutomationServer') ?Y`zg`  
    5!:._TcO  
    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 7jezw'\=~

    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: nL;K|W  
    1. 在FRED脚本编辑界面找到参考. BD1K H;  
    2. 找到Matlab Automation Server Type Library X\G)81Q.S  
    3. 将名字改为MLAPP wG:$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。 ~j}J<4&OvC

    现在将脚本代码公布如下,此脚本执行如下几个步骤: [#zE. TW  
    1. 创建Matlab服务器。 T:)% P6/  
    2. 移动探测面对于前一聚焦面的位置。 ~GYpa t  
    3. 在探测面追迹光线 6 <r2*`  
    4. 在探测面计算照度 )ys=+Pz  
    5. 使用PutWorkspaceData发送照度数据到Matlab z qO$
