Displaying Algebraic Loop Information

The atrace command causes the debugger to display information about a model's algebraic loops (see Algebraic Loops) each time they are solved. The command takes a single argument that specifies the amount of information to display.

Command
Displays for Each Algebraic Loop
atrace 0
No information
atrace 1
The loop variable solution, the number of iterations required to solve the loop, and the estimated solution error
atrace 2
Same as level 1
atrace 3
Level 2 plus the Jacobian matrix used to solve the loop
atrace 4
Level 3 plus intermediate solutions of the loop variable
