Returns the history value.
value = optimbase_histget(opt, iter, key)
The object of TOPTIM type (tlist).
An integer. The iteration number to get.
A string. The name of the key to query.
A 1-by-1 matrix of doubles. The value to get.
The optimbase_histget
function returns the history value at the given
iteration number for the given key.
If the key is unknown, this function generates an error.
The list of available keys is the same as the optimbase_histset
:
The x optimum.
The optimum cost function value.
