`MATMUL`

— matrix multiplication*Description*:- Performs a matrix multiplication on numeric or logical arguments.
*Standard*:- Fortran 95 and later
*Class*:- Transformational function
*Syntax*:`RESULT = MATMUL(MATRIX_A, MATRIX_B)`

*Arguments*:-
`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`. *Return value*:- 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. *See also*:
