4.3.1.7 Miscellaneous Features

Although AMI has a lot of useful features that simplify the process of model development, there are still some problems which turned out to be rather laborious. These problems lead to unnecessary long models that are hard to read and even harder to debug. Therefore a couple of miscellaneous features have been implemented that drastically reduce the amount of developing effort:

• analytical calculation of the determinate of a matrix

  matrix = [[a11,a12, ... , a1n]
            [a21,a22, ... , a2n]
                      ...
            [an1,an2, ... , ann]];
  detJ = |matrix|;
  

• analytical calculation of the inverse matrix (if it exists)

  InvMatrix = Inv(matrix);
  

• small equation systems can be solved analytically

  vector=[v1,v2, ... ,v_n]^T;
  SolutionVector = Solve(matrix,vector);
  

• calculation of the length of a vector

  Length=|vector|;
  

• calculation of the normal vector corresponding to two vectors (outer-product)

  NormalVector = vector1 x vector2;
  

• write debug information about any defined variable during simulation run and show its calculated result

  DEBUG: var1,var2,...,var_n
