MATMUL
— matrix multiplicationPerforms a matrix multiplication on numeric or logical arguments.
Fortran 90 and later
Transformational function
RESULT = MATMUL(MATRIX_A, MATRIX_B)
MATRIX_A | An array of INTEGER ,
REAL , COMPLEX , or LOGICAL type, with a rank of
one or two. |
MATRIX_B | An array of INTEGER ,
REAL , or COMPLEX type if MATRIX_A is of a numeric
type; otherwise, an array of LOGICAL type. The rank shall be one
or two, and the first (or only) dimension of MATRIX_B shall be
equal to the last (or only) dimension of MATRIX_A.
MATRIX_A and MATRIX_B shall not both be rank one arrays. |
The matrix product of MATRIX_A and MATRIX_B. The type and
kind of the result follow the usual type and kind promotion rules, as
for the *
or .AND.
operators.
