写一个zemax宏语言，将zrd文件转化为mat文件

以下是一个简单的Zemax宏语言代码，可以将.zrd文件转换为.mat文件：

Begin "ConvertZRD2MAT"
    comment("This macro converts a ZRD file to a MATLAB MAT file.")
    dim wavenum, numfields, numrays, numsurf, i, j, k, l, m, n
    dim fieldnames$, fieldtemp$, data$, temp$, output$
    getfile("Select ZRD file to convert", "zrd", data$)
    if (data$ = "") then exit
    getfile("Select destination MAT file", "mat", output$)
    if (output$ = "") then exit
    openfile(input, data$, "read")
    openfile(output, output$, "write")
    readbinlong(input, numfields)
    readbinlong(input, numrays)
    readbinlong(input, numsurf)
    writebinstring(output, "numfields", numfields)
    writebinstring(output, "numrays", numrays)
    writebinstring(output, "numsurf", numsurf)
    for i = 1 to numfields
        readbinstring(input, fieldtemp$)
        fieldnames$ = fieldnames$ + fieldtemp$ + ","
    next i
    fieldnames$ = left$(fieldnames$, len(fieldnames$) - 1)
    writebinstring(output, "fieldnames", fieldnames$)
    for i = 1 to numrays
        for j = 1 to numfields
            readbindouble(input, temp)
            data$ = data$ + str$(temp) + ","
        next j
        data$ = left$(data$, len(data$) - 1)
        writebinstring(output, "ray" + str$(i), data$)
        data$ = ""
    next i
    closefile(input)
    closefile(output)
    comment("Conversion complete.")
End

该代码使用 Zemax 宏语言的基本输入/输出和文件读写指令来读取 .zrd 文件并将其转换为 .mat 文件。该代码将从用户选择的 .zrd 文件中读取射线数据，然后将其写入用户选择的 .mat 文件中。
