MVar.fromlist()
fromlist ( varlist )
Convert a list of variables into an MVar object. The shape is inferred from the contents of the list - a list of Var objects produces a 1-D MVar object, a list of lists of Var objects produces a 2-D MVar, etc.
Arguments:
varlist: A list of Var objects to populate the returned MVar.
Return value:
MVar object corresponding to the input variables.
Example usage:
x0 = model.addVar() x1 = model.addVar() x2 = model.addVar() x3 = model.addVar() x_1d = MVar.fromlist([x0, x1, x2, x3]) # 1-D MVar x_2d = MVar.fromlist([[x0, x1], [x2, x3]]) # 2-D MVar
