LibreOffice Calc is the spreadsheet component of the LibreOffice software package. [6] [7]After forking from OpenOffice.org in 2010, LibreOffice Calc underwent a massive re-work of external reference handling to fix many defects in formula calculations involving external references, and to boost data caching performance, especially when referencing large data ranges.
In mathematical morphology and digital image processing, a top-hat transform is an operation that extracts small elements and details from given images.There exist two types of top-hat transform: the white top-hat transform is defined as the difference between the input image and its opening by some structuring element, while the black top-hat transform is defined dually as the difference ...
Was one of the big three spreadsheets (the others being Lotus 123 and Excel). EasyOffice EasySpreadsheet – for MS Windows. No longer freeware, this suite aims to be more user friendly than competitors. Framework – for MS Windows. Historical office suite still available and supported. It includes a spreadsheet.
The top hat function can be generated by differentiating a linear ramp function of width . The limit of ϵ {\displaystyle \epsilon } then becomes the Dirac delta function . Its real-space form is the same as the moving average , with the exception of not introducing a shift in the output function.

Paradigm, an AI agent-focused startup looking to take on Microsoft and Google in transforming spreadsheets, came out of stealth today with new funding.
The Hankel matrix transform, or simply Hankel transform, of a sequence is the sequence of the determinants of the Hankel matrices formed from . Given an integer n > 0 {\displaystyle n>0} , define the corresponding ( n × n ) {\displaystyle (n\times n)} -dimensional Hankel matrix B n {\displaystyle B_{n}} as having the matrix elements [ B n ] i ...
Mexican hat. In mathematics and numerical analysis, the Ricker wavelet, [1] Mexican hat wavelet, or Marr wavelet (for David Marr) [2] [3] = / (())is the negative normalized second derivative of a Gaussian function, i.e., up to scale and normalization, the second Hermite function.
