MATLAB下输出一个二维数组（以C语言格式）
clc;clear all;close all;
%%
%%计算DCT系数
P = 24; P2 = P/2;
for k=1:P2;
n = 0:P-1;
dctcoef(k,:) = cos((2*n+1)*k*pi/(2*P));
end
dctcoef = int16(dctcoef*2^15);
%%
%%特定格式输出到文件
fid = fopen('C:','wt'); %写入文件路径
matrix = dctcoef;
[m n] = size(matrix);
fprintf(fid,'const signed short int DCTCOEF[%d][%d]={n',m,n);
for i=1:m
fprintf(fid,'{');
for j=1:n-1
fprintf(fid,'%d,',matrix(i,j));
end
fprintf(fid,'%d},n',matrix(i,n));
end
fprintf(fid,'};');
fclose(fid);
文件夹下数据的格式如下：
const signed short int DCTCOEF[12][24]={
