Add remaining functions to ulmblas.c
Content |
There are still some functions declared in ulmblas.h that are currently not defined in ulmblas.c. These are dcopy and dgemv. Furthermore, function dlaswp is neither declared nor defined in ulmblas.h and ulmblas.c. This is supposed to be done now.
Exercise
-
Add in ulmblas.c an implementation for dgemv. You already have implemented in Session 11 functions dgemv_dotf and dgemv_axpyf. Use these two implementations as building blocks as follows:
-
If \(A\) is stored row major function dgemv calls dgemv_dotf and
-
if \(A\) is stored col major function dgemv calls dgemv_axpyf.
-
Test for gemv
Use the test program test_dgemv.c. Compile it with
heim$ gcc -Wall -std=c11 -I. -O3 -o test_dgemv test_dgemv.c ulmaux.c ulmblas.c heim$
First, check that your implementation is correct:
heim$ ./test_dgemv check
