I have a two-dimensional matrix where one of its elements depends on subject I
I create a three-dimensional matrix A where the first subscript is I.
DIMENSION A(N_SUB, N_PAR, N_PAR+1)
where N_SUB = number of subjects and N_PAR = 7
I am trying to multiply the transpose of A to a constant matrix B (7 by 7).
I would like to use the routine dmxtyf to obtain the product. This routine is supposed to multiply two two-dimensional matrices.
How can I convert A to a two-dimensional matrix so I can use the routine dmxtyf?
I tried
DIMENSION MT(N_PAR, N_PAR)
DIMENSION E(N_PAR+1,N_PAR+1)
DO 10 I = 1, N_SUB
DO 9 J = 1, N_PAR
DO 8 K =1, N_PAR+1
MT(J,K) = A(I,J,K)
8 CONTINUE
9 CONTINUE
CALLDMXTYF(7,8,MT,7,7,7,SMATINV,7,8,7,E,8)
DO 7 J=1,N_PAR+1
WRITE(20,130)(E(J,K),K=1,N_PAR+1)
7 CONTINUE
10 CONTINUE
But it gives me all zeros!
SOMEONE CAN HELP ME PLEASE.
