Matlab的fwrite()函数和fread()函数都是将从文件中读进来的数据按列顺序存放在矩阵中的。
A = FREAD(FID,SIZE) reads the number of elements specified by SIZE. Valid entries for SIZE are:
N read N elements into a column vector.
inf read to the end of the file.
[M,N] read elements to fill an M-by-N matrix, in column order.
N can be inf, but M can't.
COUNT = FWRITE(FID,A,PRECISION) writes the elements of matrix A to the specified file, translating MATLAB values to the specified precision.
The data are written in column order. COUNT is the number of elements successfully written.
