Parsing 2-D Array into Inverte Matrix error with Local Variabel

[Rafing]

Hallo Community,

sorry for the banality of my question. I want to invert a Matrix.  I feed the invert matrix function with a local variable that is feeded throw a 2 D matrix. I have looked the process throw probes up and concluded that the Inverse matrix function spits a [0x0] matrix out. Could someone show me what i have done wrong :0

thanks for your help !!!

Did you put valid data into your controls?

Right now all your controls are set at default values, including 0 for Array ?? control going to the N terminal of the For Loop.  If I put a meaningful value in there like 2, it works.  Anything else fails because you have hard coded inside that loop a 1-D array of 2 elements, so you wind up with a rectangular array that you can't invert.

• Remove the delays
• remove the local variable and branch the wire going to the blue array indicator
• Remove the sequence structure, it makes no sense.
• You can only invert a square 2D array (or matrix), so your code only works if "Array Größe"=2.
• Create a DBL array directly
• Avoid coercion dots
• You can enter error=-20040 into "menu..help..explain error" and it will tell you that "Analysis:  The input matrix must be a square matrix."

Try something like this:
