# Find the version number of a utility. The findprograms function developed in Exercise 3.7 is fine…

Find the version number of a utility. The findprograms function developed in Exercise 3.7 is fine for checking that certain utilities are available on the current computer system. However, in many occasions it is not sufficient that a particular program exists, a special version of the program might be needed. The purpose of the present exercise is to produce code segments for checking the version […]

Compute time step values in the simviz1.py script. The value of _t, unless set by the -dt command-line option, could be chosen as a fraction of T , where T is the typical period of the oscillations. T will be dominated by the period of free vibrations in the system, 2_/, or the period of the forcing term, 2_/_. Let T be the smallest of […]

# Add animations to the GUI in Exercise 11.5. The demo of Newtons method, as made in Exercise 11.5,..

Add animations to the GUI in Exercise 11.5. The demo of Newtons method, as made in Exercise 11.5, can be more illustrative by animating the graphs. Let the function graph y = f(x) be fixed, but animate the drawing of the straight line approximation. That is, start at the point (xp, f(xp)), draw the line to the next zero-crossing point (xp+1, 0) (recall that xp+1 […]

Control a layout with the grid geometry manager. Consider the following script, whose result is displayed in Figure 6.12a: #!/usr/bin/env python from Tkinter import * root = Tk() root.configure(background=gray) row = 0 for color in (red, orange, yellow, blue, green, brown, purple, gray, pink): l = Label(root, text=color, background=white) l.grid(row=row, column=0) f = Frame(root, background=color, width=100, height=2) f.grid(row=row, column=1) row = row + 1 root.mainloop() […]

# Animate a curve in a BLT graph widget. Suppose you want to explore a function f(x, t) by dragging a.

Animate a curve in a BLT graph widget. Suppose you want to explore a function f(x, t) by dragging a slider to change the t parameter and continuously see how the graph of f as a function of x moves. Make a GUI with a slider for specifying t and a BLT graph widget for plotting f as a function of x. Binding an update […]

Implement Exercise 2.9 using NumPy arrays. Solve the same problem as in Exercise 2.9, but use Numerical Python and a vectorized algorithm. That is, generate a (long) random vector e of 2n uniform integer numbers ranging from 1 to 6, find the entries that are 6 by using where(e == 6, 1, 0), reshape the vector to a two-dimensional 2 × n array, add the […]

# Fix Unix/Windows Line Ends. Text files on MS-DOS and Windows have rn at the end of lines, whereas.

Fix Unix/Windows Line Ends. Text files on MS-DOS and Windows have rn at the end of lines, whereas Unix applies only n. Hence, when moving a Unix file to Windows, line breaks may not be visible in certain editors (Notepad is an example). Similarly, a file written on a Windows system may be shown with a strange character at the end of lines in certain […]

Vectorize a constant function. The function def initial_condition(x): return 3.0 does not work properly when x is a NumPy array. In that case the function should return a NumPy array with the same shape as x and with all entries equal to 3.0. Perform the necessary modifications such that the function works for both scalar types and NumPy arrays.

Set vectorized boundary conditions in 3D grids. Most parts of the solver function in src/py/examples/pde/wave2D_func1.py are easily extended to 3D problems defined over box grids. Perhaps the only difficulty is the vectorization of the calls to the boundary condition function bc. Why does not the following trivial extension to 3D work properly? i = 0; up[i,:,:] = bc(x[i], y, z, t) Explain in detail what […]

Evaluate a function over a 3D grid. Write a class Grid3D for representing a three-dimensional uniform grid on a box with user-defined dimensions and cell resolution. The class should be able to compute a three-dimensional array of function values over the grid points, given a Python function. Here is an exemplifying code segment: g = Grid3D(xmin=0, xmax=1, dx=0.1, ymin=0, ymax=10, dy=0.5, zmin=0, zmax=2, dz=0.02) f […]
