Multiple-outer-product instruction

A multiple-outer-product instruction specifies multiple first source vector operands, at least one second source vector operand and correlation information associated with the second source vector operand(s), each vector operand comprising multiple data elements and the correlation information indicating, for each data element of a given second source vector operand, a corresponding first source vector operand. In response to the multiple-outer-product instruction, instruction decoder circuitry (50) controls processing circuitry (60) to perform computations to implement outer product operations, the outer product operations comprising, for a given first source vector operand, performing an associated outer product of that first source vector operand with a subset of data elements of the second source vector operand(s). The processing circuitry selects, for each data element of the second source vector operand(s), a corresponding first source vector operand to be used when performing the associated outer produ
