说明：  rdmseed:读取迷你种子文件 每个数据记录被导入到一个结构数组中，允许分别添加数据块和头字段(对于多通道文件很有用)，就像用一个简单的cat(1,X.d)函数连接所有数据一样。时间戳也被转换为Matlab datenum格式。该函数使用两种常用的压缩格式Steim-1和Steim-2来读取“仅数据”的迷你种子。通用FDSN格式也得到了实现(ASCII、16/24/32位整数、IEEE浮点数和双数)，以及GEOSCOPE多路复用旧格式(24位、16/3或16/4位增益范围)。所有这些格式都应该能够工作，但其中一些还没有使用真实数据进行测试。我还部分编码了Steim-3格式，但没有明确的描述和任何文件示例……由于我从未遇到过使用这种格式的数据文件，我不知道它是否真的有用。 该函数还自动检测大/小端编码文件。
(rdmseed: reading miniSEED file Each data record is imported into a structure array, allowing to adress data blocks and header fields individually (useful for multi-channel files), just as concatenating all data with a simple cat(1,X.d) function. Time stamps are also converted into Matlab datenum format. The function reads miniSEED "data-only" using the two mostly used compression formats Steim-1 and Steim-2. General FDSN formats have also been implemented (ASCII, 16/24/32-bit integers, IEEE floats and doubles), and GEOSCOPE multiplexed old formats (24-bit, 16/3 or 16/4-bit gain ranged). All these formats should work but some of them have not been tested using real data. I also partly coded Steim-3 format but without a clear description and any file example... Since I never met any data file using this format, I don't know if it's really useful.)
