Steven Chapra’s utilized Numerical equipment with MATLAB, 3rd version, is written for engineering and technological know-how scholars who have to examine numerical challenge fixing. idea is brought to notify key thoughts that are framed in functions and tested utilizing MATLAB. The ebook is designed for a one-semester or one-quarter path in numerical tools generally taken through undergraduates. The 3rd variation positive aspects new chapters on Eigenvalues and Fourier research and is followed by way of an in depth set of m-files and teacher fabrics.

Example text

For the markers, the default size is 6 point with blue edge color and no face color. MATLAB allows you to display more than one data set on the same plot. For example, an alternative way to connect each data marker with a straight line would be to type >> plot(t, v, t, v, 'o') It should be mentioned that, by default, previous plots are erased every time the plot command is implemented. The hold on command holds the current plot and all axis properties so that additional graphing commands can be added to the existing plot.

Again, this is physically correct as the positive drag force acts downward against the upward negative velocity. Unfortunately, for this case, Eq. 7) yields a negative drag force because it does not include the unit directional vector. In other words, by squaring the velocity, its sign and hence its direction is lost. Consequently, the model yields the physically unrealistic result that air resistance acts to accelerate an upward velocity! In this case study, we will modify our model so that it works properly for both downward and upward velocities.

1 Thus, if we measure the terminal velocity of a number of jumpers of known mass, this equation provides a means to estimate the drag coefficient. 1 were collected for this purpose. In this chapter, we will learn how MATLAB can be used to analyze such data. Beyond showing how MATLAB can be employed to compute quantities like drag coefficients, we will also illustrate how its graphical capabilities provide additional insight into such analyses. 1 THE MATLAB ENVIRONMENT MATLAB is a computer program that provides the user with a convenient environment for performing many types of calculations.
