# Solving Nonlinear Systems¶↑

For linear systems, see Matrix.solv().

prmat()

Prints the form of the matrix defined by eqn statements. Each nonzero element is printed as an “*”.

solve()

Does one iteration of the non-linear system defined by eqn statements. Returns the linear norm of the difference between left and right hand sides plus the change in the dependent variables.

eqinit()

Throws away previous dependent variable and equation specifications from eqn statements.
