+
+**csaps** is a Python package for univariate, multivariate and n-dimensional grid data approximation using cubic smoothing splines.
+The package can be useful in practical engineering tasks for data approximation and smoothing.
+
+## Installing
+
+Use pip for installing:
+
+```
+pip install -U csaps
+```
+
+The module depends only on NumPy and SciPy. Python 3.6 or above is supported.
+
+## Simple Examples
+
+Here is a couple of examples of smoothing data.
+
+An univariate data smoothing:
+
+```python
+import numpy as np
+import matplotlib.pyplot as plt
+
+from csaps import csaps
+
+np.random.seed(1234)
+
+x = np.linspace(-5., 5., 25)
+y = np.exp(-(x/2.5)**2) + (np.random.rand(25) - 0.2) * 0.3
+xs = np.linspace(x[0], x[-1], 150)
+
+ys = csaps(x, y, xs, smooth=0.85)
+
+plt.plot(x, y, 'o', xs, ys, '-')
+plt.show()
+```
+
+<p align="center">
+ <img src="https://user-images.githubusercontent.com/1299189/72231304-cd774380-35cb-11ea-821d-d5662cc1eedf.png" alt="univariate" />
+<p/>
+
+A surface data smoothing:
+
+```python
+import numpy as np
+import matplotlib.pyplot as plt
+from mpl_toolkits.mplot3d import Axes3D
+
+from csaps import csaps
+
+np.random.seed(1234)
+xdata = [np.linspace(-3, 3, 41), np.linspace(-3.5, 3.5, 31)]
+i, j = np.meshgrid(*xdata, indexing='ij')
+ydata = (3 * (1 - j)**2. * np.exp(-(j**2) - (i + 1)**2)
+ - 10 * (j / 5 - j**3 - i**5) * np.exp(-j**2 - i**2)
+ - 1 / 3 * np.exp(-(j + 1)**2 - i**2))
+ydata = ydata + (np.random.randn(*ydata.shape) * 0.75)
+
+ydata_s = csaps(xdata, ydata, xdata, smooth=0.988)
+
+fig = plt.figure(figsize=(7, 4.5))
+ax = fig.add_subplot(111, projection='3d')
+ax.set_facecolor('none')
+c = [s['color'] for s in plt.rcParams['axes.prop_cycle']]
+ax.plot_wireframe(j, i, ydata, linewidths=0.5, color=c[0], alpha=0.5)
+ax.scatter(j, i, ydata, s=10, c=c[0], alpha=0.5)
+ax.plot_surface(j, i, ydata_s, color=c[1], linewidth=0, alpha=1.0)
+ax.view_init(elev=9., azim=290)
+
+plt.show()
+```

+## Documentation
+
+More examples of usage and the full documentation can be found at https://csaps.readthedocs.io.
+
+## Testing
+
+We use pytest for testing.
+
+```
+cd /path/to/csaps/project/directory
+pip install -e .[tests]
+pytest
+```
+
+## Algorithm and Implementation
+
+**csaps** Python package is inspired by MATLAB [CSAPS](https://www.mathworks.com/help/curvefit/csaps.html) function that is an implementation of
+Fortran routine SMOOTH from [PGS](http://pages.cs.wisc.edu/~deboor/pgs/) (originally written by Carl de Boor).
+
+Also the algothithm implementation in other languages:
+
+* [csaps-rs](https://github.com/espdev/csaps-rs) Rust ndarray/sprs based implementation
+* [csaps-cpp](https://github.com/espdev/csaps-cpp) C++11 Eigen based implementation (incomplete)

+More examples of usage and the full documentation can be found at https://csaps.readthedocs.io.
+
+## Testing
+
+We use pytest for testing.
+
+```
+cd /path/to/csaps/project/directory
+pip install -e .[tests]
+pytest
+```
+
+## Algorithm and Implementation
+
+**csaps** Python package is inspired by MATLAB [CSAPS](https://www.mathworks.com/help/curvefit/csaps.html) function that is an implementation of
+Fortran routine SMOOTH from [PGS](http://pages.cs.wisc.edu/~deboor/pgs/) (originally written by Carl de Boor).
+
+Also the algothithm implementation in other languages:
+
+* [csaps-rs](https://github.com/espdev/csaps-rs) Rust ndarray/sprs based implementation
+* [csaps-cpp](https://github.com/espdev/csaps-cpp) C++11 Eigen based implementation (incomplete)

+# Changelog
+
+## v1.1.0
+
+* Introduced optional `normalizedsmooth` argument to reduce dependence on xdata and weights [#47](https://github.com/espdev/csaps/pull/47)
+* Update numpy and scipy dependency ranges
+
+## v1.0.4 (04.05.2021)
+
+* Bump numpy dependency version
+
+## v1.0.3 (01.01.2021)
+
+* Bump scipy dependency version
+* Bump sphinx dependency version and use m2r2 sphinx extension instead of m2r
+* Add Python 3.9 to classifiers list and to Travis CI
+* Set development status classifier to "5 - Production/Stable"
+* Happy New Year!
+
+## v1.0.2 (19.07.2020)
+
+* Fix using 'nu' argument when n-d grid spline evaluating [#32](https://github.com/espdev/csaps/pull/32)
+
+## v1.0.1 (19.07.2020)
+
+* Fix n-d grid spline evaluating performance regression [#31](https://github.com/espdev/csaps/pull/31)
+
+## v1.0.0 (11.07.2020)
+
+* Use `PPoly` and `NdPPoly` base classes from SciPy interpolate module for `SplinePPForm` and `NdGridSplinePPForm` respectively.
+* Remove deprecated classes `UnivariateCubicSmoothingSpline` and `MultivariateCubicSmoothingSpline`
+* Update the documentation
+
+**Notes**
+
+In this release the spline representation (the array of spline coefficients) has been changed
+according to `PPoly`/`NdPPoly`.
+See SciPy [PPoly](https://docs.scipy.org/doc/scipy/reference/generated/scipy.interpolate.PPoly.html)
+and [NdPPoly](https://docs.scipy.org/doc/scipy/reference/generated/scipy.interpolate.NdPPoly.html) documentation for details.
+
+
+## v0.11.0 (28.03.2020)
+
+* Internal re-design `SplinePPForm` and `NdGridSplinePPForm` classes [#17](https://github.com/espdev/csaps/issues/17):
+ - Remove `shape` and `axis` properties and reshaping data in these classes
+ - `NdGridSplinePPForm` coefficients array for 1D grid now is 1-d instead of 2-d
+* Refactoring the code and decrease memory consumption
+* Add `overload` type-hints for `csaps` function signatures
+
+## v0.10.1 (19.03.2020)
+
+* Fix call of `numpy.pad` function for numpy <1.17 [#15](https://github.com/espdev/csaps/issues/15)
+
+## v0.10.0 (18.02.2020)
+
+* Significant performance improvements for make/evaluate splines and memory consumption optimization
+* Change format for storing spline coefficients (reshape coeffs array) to improve performance
+* Add shape property to `SplinePPForm`/`NdGridSplinePPForm` and axis property to `SplinePPForm`
+* Fix issues with the smoothing factor in nd-grid case: inverted ordering and unnable to use 0.0 value
+* Update documentation
+
+## v0.9.0 (21.01.2020)
+
+* Drop support of Python 3.5
+* `weights`, `smooth` and `axis` arguments in `csaps` function are keyword-only now
+* `UnivariateCubicSmoothingSpline` and `MultivariateCubicSmoothingSpline` classes are deprecated
+ and will be removed in 1.0.0 version. Use `CubicSmoothingSpline` instead.
+
+## v0.8.0 (13.01.2020)
+
+* Add `csaps` function that can be used as the main API
+* Refactor the internal structure of the package
+* Add the [documentation](https://csaps.readthedocs.io)
+
+**Attention**
+
+This is the last version that supports Python 3.5.
+The next versions will support Python 3.6 or above.
+
+## v0.7.0 (19.09.2019)
+
+* Add Generic-based type-hints and mypy-compatibility
+
+## v0.6.1 (13.09.2019)
+
+* A slight refactoring and extra data copies removing
+
+## v0.6.0 (12.09.2019)
+
+* Add "axis" parameter for univariate/multivariate cases
+
+## v0.5.0 (10.06.2019)
