1.功能
用全選主元高斯消去法計算矩陣A的秩(C語言)
2.函數(shù)參數(shù)說明
double a[m][n] : 存放mxn階矩陣A的元素，返回時將被破壞
int m : 矩陣A的行數(shù)
int n : 矩陣A的列數(shù)
int rank() : 函數(shù)返回A的秩
3.文件說明
rank.c為函數(shù)程序
rank0.c為主函數(shù)程序

％ xtrain: (Ltrain,N) with Ltrain: number of points N: dimension
％ ytrain: (Ltrain,1) containing class labels (-1 or +1)
％ xrun: (Lrun,N) with Lrun: number of points N: dimension
％ atrain: alpha coefficients (from svcm_train on xtrain and ytrain)
％ btrain: offest coefficient (from svcm_train on xtrain and ytrain)
