    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。 <1D|TrP  
    u5(8k_7  
    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: *VZ|Idp  
    enableservice('AutomationServer', true) /,Xl8<~#  
    enableservice('AutomationServer') &]nx^C8V;  
    iVXt@[  
    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 HC%Hbc~S_Q

    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: 5?kfE  
    1. 在FRED脚本编辑界面找到参考. fjh|V9H  
    2. 找到Matlab Automation Server Type Library E(jZ Do  
    3. 将名字改为MLAPP 6>a6;[

    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。 b2m={q(s

    2. 移动探测面对于前一聚焦面的位置。 53HA6:Q[  
    3. 在探测面追迹光线 :GXF=Df  
    4. 在探测面计算照度 =@HS  
    5. 使用PutWorkspaceData发送照度数据到Matlab a+w2cN'  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 6Y9N= \`  
    7. 用Matlab画出照度数据 No^gKh24  
    8. 在Matlab计算照度平均值 Nd~B$venh  
    9. 返回数据到FRED中 X0lPRk53(
