Hi,

I would like to use the complex lookup table in polar form instead of real / imag notation. I tried polarcpx(polar(1,90)) but it does not work.

Any idea. Thanks Wolfram???

you are write. It works. The touble comes with the value array being in a variable. It leads to a segmentation error. But specifying the values directly in the table is working.

Thank you. Wolfram

I was too fast. Instead of polar(x,y) I used (x,y) which is a correct notation but not what I want. As soon as I add polar() or polarcpx() I get errors.

You should use reference (@) in this case.

If you'd like to specify the value in the parameter dialog box, use @polar(x,y) or @{polar(x,y), polar(y,x)} (for multiply values).

You can also specify the value directly on the schematic, type in polar(x,y) or {polar(x,y), polar(y,x)} (for multiply values) after the "=".

now it is working. Excellent.

Thank you Wolfram
