* and /

Arithmetic multiplication and division operate element-wise in AUX. For arrays and audio signals, this corresponds to MATLAB-style dot multiplication rather than matrix multiplication.

Syntax

z = x * y
z = x / y

Operands and Result

Allowed types: SCAL, VCT, AUD, TEXT, TSEQ, NUL
Not allowed: CLASS, CELL

Typical supported combinations include scalar-array, scalar-audio, vector-vector, vector-audio, audio-audio, scalar-time-sequence, and time-sequence-time-sequence operations.

Notes

• This is element-wise arithmetic, not matrix multiplication.
• For SCAL * VCT and SCAL * AUD, the scalar is applied to the entire array or signal.
• For VCT * VCT and VCT * AUD, the operation proceeds while both operands have values available.
• For AUD * AUD, the operation is time-based and is applied wherever both signals are present.
• For SCAL * TSEQ, the scalar multiplies the value of the time sequence at each time point.
• For TSEQ * TSEQ, both operands must have the same number of time points, although the actual times do not need to match.
• TSEQ * AUD multiplies the audio signal by a linearly interpolated version of the time sequence.
• When both operands are grouped as matrices, they must have the same number of groups (rows).
• Multiplication is commutative. Division is not.
