is_inside_bounds

odl.tomo.util.utility.is_inside_bounds(value, params)[source]

Return True if value is contained in params.

This method supports broadcasting in the sense that for params.ndim >= 2, if more than one value is given, the inputs are broadcast against each other.

Parameters
valuearray-like

Value(s) to be checked. For several inputs, the final bool tells whether all inputs pass the check or not.

paramsIntervalProd

Set in which the value is / the values are supposed to lie.

Returns
is_inside_boundsbool

True is all values lie in params, False otherwise.

Examples

Check a single point:

>>> params = odl.IntervalProd([0, 0], [1, 2])
>>> is_inside_bounds([0, 0], params)
True
>>> is_inside_bounds([0, -1], params)
False

Using broadcasting:

>>> pts_ax0 = np.array([0, 0, 1, 0, 1])[:, None]
>>> pts_ax1 = np.array([2, 0, 1])[None, :]
>>> is_inside_bounds([pts_ax0, pts_ax1], params)
True
>>> pts_ax1 = np.array([-2, 1])[None, :]
>>> is_inside_bounds([pts_ax0, pts_ax1], params)
False
