nlcpy.resize(a, new_shape)[ソース]

Returns a new array with the specified shape.

If the new array is larger than the original array, then the new array is filled with repeated copies of a. Note that this behavior is different from a.resize(new_shape) which fills with zeros instead of repeated copies of a.


Array to be resized.

new_shapeint or sequence of ints

Shape of resized array.


The new array is formed from the data in the old array, repeated if necessary to fill out the required number of elements. The data are repeated in the order that they are stored in memory.


Warning: This functionality does not consider axes separately, i.e. it does not apply interpolation/extrapolation. It fills the return array with the required number of elements, taken from a as they are laid out in memory, disregarding strides and axes. (This is in case the new shape is smaller. For larger, see above.) This functionality is therefore not suitable to resize images, or data where each axis represents a separate and distinct entity.


>>> import nlcpy as vp
>>> a=vp.array([[0,1],[2,3]])
>>> vp.resize(a,(2,3))
array([[0, 1, 2],
       [3, 0, 1]])
>>> vp.resize(a,(1,4))
array([[0, 1, 2, 3]])
>>> vp.resize(a,(2,4))
array([[0, 1, 2, 3],
       [0, 1, 2, 3]])
