我正在尝试计算:C = 1*(A*B') + 0*C
使用 cblas_dgemm()。据我所知,参数是正确的。错误消息本身没有意义:
"ldb must be >= MAX(K,1): ldb=3 K=3Parameter 11 to routine cblas_dgemm was incorrect"
但是,ldb = k = 3!这是所有三个矩阵和参数的详细输出。
A: (m x n: 4x3), lda = 4
B': (n x k: 3x9), lda = 3
C: (m x k, 4x9), ldc = 4

Transpose A ta = 111 (CblasNoTrans)
Transpose B tb = 112 (CblasTrans)
m = 4, k = 3, n = 9
lda = 4, ldb = 3, ldc = 4
alpha = 1, beta = 0
CALLING CBLAS_DGEMM:
cblas_dgemm( CblasColMajor, ta, tb, m, n, k, alpha, A->d, lda, B->d, ldb, beta, C->d, ldc );
我确定我犯了一个愚蠢的错误,我只是无法发现它。任何帮助将不胜感激。
非常感谢,
