Display the result. This is often referred to as a "two by three matrix", a "23-matrix", or a matrix of dimension 23.Without further specifications, matrices represent linear maps, and allow explicit computations in linear algebra.Therefore, the study of matrices is a large part of linear algebra, and most properties and operations of abstract Note that np.where with one argument returns a tuple of arrays (1-tuple in 1D case, 2-tuple in 2D case, etc), thus you need to write np.where(a>5)[0] to get np.array([5,6,7]) in the example above (same for np.nonzero).. Vector operations. Here 1 is the first non-singleton dimension (the dimension whose length is not equal to 1). For images of data type double, the default display range is [0, 1]. This argument does not guarantee that the contour contracts or expands.

At the left end, fix the first derivative of the spline to have a value of 1. The boundaries of the object regions (white) in using the createMask function.
