To create a 2 D Gaussian array using the Numpy python module. My rule of thumb is to use $5\sigma$ and be sure to have an odd size. A reasonably fast approach is to note that the Gaussian is separable, so you can calculate the 1D gaussian for x and y and then take the outer p...
F-Graph also works as a scientific calculator. You may enter the calculation clicking on the buttons of the application pad or directly directly enter the expression as text. Press = to perform the calculation. The calculator supports multiple level of parentheses. A parenthesis is automatically ap...

Any scientific calculator, high-level programming language, or math package will have internally generated functions to evaluate such standard mathematical functions. While not all scientific calculators and high-level programming languages have internally generated functions for evaluating Gaussian CDFs, most...
