    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。 6.5E d-  
    u|(;SY  
    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: X6 E^5m  
    enableservice('AutomationServer', true) hNU$a?eVpR  
        enableservice('AutomationServer') F^4mO|  
    (-S\%,hO  
    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 'aV])(Wm>  
    f[1 s4Dp3-  
    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: p.@ kv  
    1. 在FRED脚本编辑界面找到参考. Y]!WPJ`f2  
    2. 找到Matlab Automation Server Type Library gug9cmA/Q7  
        3. 将名字改为MLAPP "t0l)P*C}  
         Z=R 6?jU*n  
         t?Ku6Z'  
    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。 65]>6D43

    2. 移动探测面对于前一聚焦面的位置。 ~cv322N   
    3. 在探测面追迹光线 mY= Q#nG  
    4. 在探测面计算照度 M:M"7>:
