file - Matlab:如何从文件中读取二进制数？

Question

文件包含由换行符分隔的二进制数。

$ cat bin_MCS.txt |tail
000000001100000000000010000000000
000000010010000000000010000000000
000011000000000000000000000000000

Matlab读取DEC二进制数，错误

>> textread('bin_MCS.txt')

ans =

   1.0e+30 *

    0.0000
    0.0000
    0.0000
    0.0000
    0.0000
    0.0000
    0.0000
    0.0000
    0.0000
    0.0000
    0.0000
    0.0000
    0.0000

目标

I need to read the binary numbers to a matrix like this [1 0 1;0 1 1]. The first puzzle is to be able to read the binary numbers. Then the next puzzle is to be able to read them in a certain format.

Answer 1

读取为字符串，然后使用 bin2dec 转换为十进制数:

bin2dec(textread('bin_MCS.txt','%s'))

ans =

    25166848
    37749760
   402653184
   335544320
   671088640
   603979776
   553649152
   100664320
   167773184
   285213696

编辑:

要将各个二进制数字读入矩阵，您可以使用它(48 是“0”的 ASCII 代码):

cell2mat(textread('bin_MCS.txt','%s'))-48
