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.
