C程序调用lapack函数

[shadowtwinkle]

When calling the dgbtrs' function of LAPACK, there is a DGER function. How should the parameter 1 be passed? When I passed it, I tried many methods, saying that the parameter was illegal. dger_(&lm,&(*NRHS),-ONE,AB_2[(kd+1)*j],1,B[j],&(*LDB),B[j+1],&(*LDB)); On entry to DGER parameter number 5 had an illegal value
