* operation in the simple DSP

assuming that the input to the simple DSP box is a matrix X and we write the expression X*X as the Equation.

does the * operation in the simple DSP box mean matrix multiplication or is it an element-wise multiplication?

Hi Kiyarash,

its an element-wise multiplication. All the operators (+,-,*,/) of Simple DSP are elementwise.

- If you need 'constant matrix * X', you can get this from the Spatial Filter box (the filter is the constant matrix).
- If you need matrix product 'X*Y' or 'X*X' for matrix chunks, this would need to be developed, afaik.
