bitshift(A, k)函数:先把A变成二进制数,然后把这个二进制数向左移动k位(如果k是负数,表示向右移动k位),再把得到的二进制数所对应的十进制数返回出来。比如,3的二进制是11,向左移一位是110,十进制就是6;向左移两位是1100,十进制就是12,如下图所示: 又例如: for
intout=bitshift(A,k)返回向左偏移k位的A,这等效于乘以 2k。k的负值与向右移位或除以 2|k|并向负无穷舍入到最接近的整数相对应。将截断任何溢出位。 如果A是有符号的整数数组,则bitshift返回算数偏移结果,并在k为负时保留有符号的位,k为正时不保留有符号的位。 如果k为正,MATLAB®将位左移,并在右侧插...
