Hello,

How I can enter a third index on a matrix? I am trying to enter "h".
I press comma (,) after "j" but I get something different.

Thank you,
Basile

Hi,

using the keyboard shortcuts you need to select the entire variable, then you can insert the 3rd index...

f.e. type: variableName [ 2 [ 3 -> [

to create the reference for the nested matrix ("->" is the right arrow)

[MATH lang=eng]el(el(variableName,2,3),#)[/MATH]

using function names you need to write: el(el(variableName,2,3),1)

Hello,

The three elements (resistors) should give me 27 values (2x3x3) in a 3 dimensional space.
I expect to get the matrix in 2 dimensional 3x3=9 with three elements each element of the 3x3 matrix.
I do not.
Any help?
The two resistor case works fine.

Thanks,
Basile
