Parameters

TransA
Type: SystemChar
Transposition state for matrix A: one of the constants in enum CBlas_Transpose
TransB
Type: SystemChar
Transposition state for matrix B: one of the constants in enum CBlas_Transpose
M
Type: SystemInt32
Number of rows in A
N
Type: SystemInt32
Number of columns in B
K
Type: SystemInt32
Number of columns in A and number of rows in B
alpha
Type: SystemDouble
multiplication factor for A
A
Type: SystemIntPtr
pointer to array A
lda
Type: SystemInt32
distance between first elements of each column for column based orientation or distance between first elements of each row for row based orientation for matrix A
B
Type: SystemIntPtr
pointer to array B
ldb
Type: SystemInt32
distance between first elements of each column for column based orientation or distance between first elements of each row for row based orientation for matrix B
beta
Type: SystemDouble
multiplication faktor for matrix B
C
Type: SystemDouble*
