c - usage of lda and ldb in sgemm matrix mulitiplication function -


while debugging matrix multiplication error, arrived @ atlas code. code looks complex , don't want further inside.(no time.. :) ) it's general matrix multiplication alpha*a*b + beta*c , guess result stored in c.(or or b..i'm not sure)

https://sourcecodebrowser.com/atlas/3.6.0/_a_t_l___sgemm_8c_source.html

could explain how lda , ldb (lead dimension of , b) used? wonder when m, n, k specifies matrix dimension information why lda , ldb needed. question : inside atl_sgemm function, atl_sgemm function being called. called recursive function?
