Overview

Matrix multiplications in which matrix A has data elements of complex 32 bit and matrix B has data elements of complex 32 bit. These operations are emulated on top of Multiply-accumulate of 32b x 16b complex integer datatypes and might not have optimal performance.

For an explanation how these operations works see Multiply Accumulate.
