在Matlab中读取半精度浮点数（float16 IEEE 754r）二进制数据
[英]Read half precision float (float16 IEEE 754r) binary data in matlab
问题描述
you have been a great help last time, i hope you can give me some advise this time, too. 
上次您的帮助很大，希望这次也能给我一些建议。
I read a binary file into matlab with bit16 (format = bitn) and i get a string of ones and zeros. 我用bit16（format = bitn）将一个二进制文件读入matlab，得到一串一和零。
bin = '1,00011,1111111111' (16 bits: 1. sign, 2-6. exponent, 7-16. mantissa) bin = '1,00011,1111111111' （16位：1。符号，2-6。指数，7-16。尾数）
According to ftp://www.fox-toolkit.org/pub/fasthalffloatconversion.pdf it can be converted like 根据ftp://www.fox-toolkit.org/pub/fasthalffloatconversion.pdf，它可以像
out = (-1)^bin(1) * 2^(bin(2:6)-15) * 1.bin(7:16) [are exponent and mantissa still binary?] out = (-1)^bin(1) * 2^(bin(2:6)-15) * 1.bin(7:16) [指数和尾数是否仍为二进制？]
Can someone help me out and tell me how to deal with the 'eeeee' and '1.mmmmmmmmmm' as mentioned in the pdf, please. 有人可以帮我一下，告诉我如何处理pdf中提到的'eeeee'和'1.mmmmmmmmmm'。
Thanks a lot! 非常感谢！
