## Main Question or Discussion Point

Dear frnds,

suppose one have a 3D matrix,

A=ones(3,3,3);

he wants to have eigen value of A,

then,

A-Lamda*I=0 where A is 3D matrix, I is 3D matrix.

now

Problem is our mathematical soft can only do 2D inversion or eigen calculation.

Please refer me any info to find out the eigenvalue of 3d matrix.

thanks anyway.
