Definition Of Manifest Function
This class can be used to plot a graphic of a function given its expression.It can evaluate the given function for a given interval of x and y variable values and draw lines between the calculated points.The class also draws a grid of scale values as well the X and Y axis.More than one graphic...

While evolving code, there is often a need to enrich an existing simple return scheme of a function by extra/optional return values. Using (variable lenght) return tuples often introduces puzzles - and the pychecker yells. In such cases the RICHVALUE recipe offers a transparent method for adding...

In order to optimize any MATLAB function, there are two options: 1) rewrite the function to take only 1 array of inputs, reading all others from a file, perhaps, or from a global variable (undesirable), or 2) write an interface layer that handles this.This function provides an interface layer...
