Q: Different FFT spectrum - jit.matrix, jit.glue, jit.world

Yoonho Kim's icon

Hi folks, I can't figure this issue out.

  1. I want spectrum 1 and 2 to show on row 1 and 2.

    However, if I connect them to jit.glue, this issue turns up.


    2. Why is jit.world shown like this?

Could you help me out please?

The error message is quite self explanatory, the matrices you send into [jit.glue] don't have the same number of planes, hence the error message. Another problem is that they don't have the same dimension either.

Spectrum 1 is a 1 plane 1x256 matrix.

Spectrum 2 is a 3 planes 250x256 matrix.

You want them both with 1 or 3 planes and with the same dimension (preferably the largest one in your case).

Here I made them both 3 planes 256x56

Oh and you had the wrong number of rows and columns in your [jit.glue]

[jit.fpsgui] is useful to debug such situations.
