Problem calculating initval of any model

Hello, I’m a new user of Dynare and have a problem to calculate the initval of any model. I do not understand how to do it .Is there any examples to help me please? also i would like to know how create my own file on matlab to calculate the steady state. If i use a model of 20 equations for exp it will be difficult to calculate the initval by hand?
Thank you !

See my Guide to Observation Equations on my homepage for advice on initval vs. steady state files. There you will also find an example for using a steady state file with the steady_state_model block.
