    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。 =&kd|o/i  
    vjfV??XSU  
    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: Gag=GHG  
    enableservice('AutomationServer', true) G}MJWf Hl  
    enableservice('AutomationServer') 5.1 c#rL  
    \YV`M3O  
    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 ~7$NVKE

    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: w 0V=49  
    1. 在FRED脚本编辑界面找到参考. Sb9O#$89  
    2. 找到Matlab Automation Server Type Library l]pHj4`uv  
    3. 将名字改为MLAPP )0RznFJ+X

    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。 8SJi~gV

    现在将脚本代码公布如下,此脚本执行如下几个步骤: wOhiC$E46  
    1. 创建Matlab服务器。 :E$<!q  
    2. 移动探测面对于前一聚焦面的位置。 Sdk:-Zuv  
    3. 在探测面追迹光线 w_O3];  
    4. 在探测面计算照度 u0Nag=cU  
    5. 使用PutWorkspaceData发送照度数据到Matlab v5aHe_?lp  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 $)V_oQSqn  
    7. 用Matlab画出照度数据 G)vq+L5%  
    8. 在Matlab计算照度平均值 h x _,>\@  
    9. 返回数据到FRED中 ?3X(`:KB
