MATLAB读写txt文件，并对数据进行二/十/十六进制转换（量化）

clear;
close all;

% 读取数据txt（任意进制、整型、浮点型）
fileID1 = fopen('D:\设计文档\dataset1_I.txt','r');
[dat_i]=textscan(fileID1,'%f');
fclose(fileID1);

fileID2 = fopen('D:\设计文档\dataset1_Q.txt','r');
[dat_q]=textscan(fileID2,'%f');
fclose(fileID2);

% cell转化为数组
dat_i_h = cell2mat(dat_i);
dat_q_h = cell2mat(dat_q);

% 量化为十进制有符号数（含符号位共14bit）
m = max(max(abs(dat_i_h),abs(dat_q_h)));
DATA_I = round(dat_i_h/m*(2^(14-1)-1));
DATA_Q = round(dat_q_h/m*(2^(14-1)-1));

% 将十进制数据写入txt
fileID_I = fopen('D:\intel_pro\RadarECG\rtl\dataset1_I_dec.txt','w');
if fileID_I == -1
　　disp('fopen failed');
else
