concatenate ( tup, axis )

Join a sequence of arrays along an existing axis.

This method has the same behavior as numpy.concatenate, except that it always returns a gurobipy matrix-friendly API object of the appropriate type.


tup: A sequence of matrix-friendly API objects

axis: The axis along which the arrays will be joined. If axis is None, arrays are flattened before use. Default is 0.

Return value:

Returns a matrix-friendly API object. Note that the return type depends on the types of the input objects.

Example usage:

X = model.addMVar((k, n))
Y = model.addMVar((k, m))
XY = gp.concatenate((X, Y), axis=1)  # (k, n+m) MVar
