Dimensions does not match in the Kalman Filter.

prog_algs/src/prog_algs/state_estimators/kalman_filter.py

Lines 119 to 126 in 8689c09

	inputs = np.array([u[key] for key in self.model.inputs])
	# Add row of ones (to account for constant E term)
	if np.size(inputs) == 0:
	inputs = np.array([[1]])
	else:
	inputs = np.append(inputs, [[1]], 0)

The variable inputs defined in Line 119 is a array whose shape is (n, ).
Exceptions will be raised then from Line 125 because [[1]] is a matrix whose shape is (1, 1) that does not match with inputs.
All the examples are based on the ThrownObject class whose inputs is empty.
So you may don't notice this problem when test your code.

Hi @CuiiGen, thanks for notifying us of this issue. We have pushed a hot fix v1.4.2, and the updated code can be installed using the standard pip install prog_algs.
