我要将文件中的矩阵导入到c程序中
请问文件中矩阵的格式应该是怎样的
如我的程序中文件导入和读取矩阵部分是这样的：
if ((stream = fopen(argv[1],"r")) == NULL)
{
fprintf(stderr, "Program %s : cannot open file %s\n",
argv[0], argv[1]);
fprintf(stderr, "Exiting to system.");
exit(1);
data = matrix(n, m);
for (i = 1; i <= n; i++)
{
for (j = 1; j <= m; j++)
{
fscanf(stream, "%f", &in_value);
data[i][j] = in_value;
}
}
txt文档中矩阵的格式如下：
101.5 100.4 97.0 98.7 100.8 114.2 104.2

104.3 98.7 100.2 116.1 105.2 101.6 102.6
为什么显示出来的全是0呢

并不是全是零
就是在c程序运行后显示的矩阵跟我的txt文档中不一样
