Matlab image processing Day5:
1, bitget () function:
% Personal feel biget () function can be roughly divided into two categories: 1, from the low to high output mode 2, the output from the high to low mode
<I>, the low to high output fixation mode bitget (x, m: n);% Parameters: x is to be converted into binary numbers, the lower output from the low bit to the m n-bit digital
Sample：
< II>, the output from the high to the low fixed pattern bitget (x, m: -1: n);
% Parameters: x same meaning as above, m represents the first of several high from the beginning, I think we can put 1 in here understood as a marker to let the output of the median descending output (default is on the way, does not require labeling)
% N represents an output from a high to low to m n bits (i.e.: if m = 4, n = 3, the outputs 3 and 4)
Sample:
% Ps: because no function definition content to see the written test data are based on the conclusions, there may be discrepancy with the actual situation, purely personal opinion

Matlab, how to extract a bit of a binary number
代码：
a=100; %十进制
b=dec2bin(a) %变成二进制字符串
c=b(1) %下标引用所需要的位值
