[Ok,Miss] = chkmissing(M,D,Start)
M [ model ] - Model object.
D [ struct ] - Input database for the simulation.
Start [ numeric ] - Start date for the simulation.
Ok [ true | false ] - True if the input database D contains all required initial values for simulating model M from date Start.
Miss [ cellstr ] - List of missing initial values.
'error=' [ true | false ] - Throw an error if one or more initial values are missing.This function does not perform any simulation; it only checks for missing initial values in an input database.
