Question

5. (10 pts) The following table shows data from a chemical reactor as a reaction is taking place. The concentration of the reactant is monitored as a function of time. 10 20 30 40 50 60 70 80 90 100 Time (s) Concentration (mg/L) 100 36.8 135 5 18 17 1.6 1.5 1.4 1.3 1.2 write a MATLAB script to generate a plot of concentration (y-axis) vs. time (x-axis). Use a black solid line with a circle as the marker. Add axis labels and a title.

Matlab

Answer 1

To plot the graph of a function, you need to take the following steps −

• Define x, by specifying the range of values for the variable x, for which the function is to be plotted

• Define the function, y = f(x)

• Call the plot command, as plot(x, y)

Matlab Code :

x = [0:10:20:30:40:50:60:70:80:90:100];
y = [100:36.8:13.5:5:1.8:1.7:1.6:1.5:1.4:1.3:1.2];

plot(x, y,'-ko'), xlabel('Time(s)'), ylabel('Concentration(mg/L)'), title('Chemical Reactor Data'),grid on, axis equal

Note : You can also use the other options as per the below table :

Line Style Specifiers You indic ate the line styles, marker types, and colors you want to display, detailed in the following tables Specifier Line Style Solid line (default) Dashed line Dotted line Dash-dot line

Color Specifiers Color Red Green Blue Cyan Magenta Yellow Black White Specifier Related Properties This page also describes how to specify the properties of lines used for plotting. MATLAB graphics give you control over these visual characteristics .Linewidth-Specifies the width (in points) of the line .MarkerEdgeColor Specifies the color of the marker or the edge color for filled markers (circle, square, diamond, pentagram, hexagram, and the four triangles). .MarkerFaceColor-Specifies the color of the face of filled markers .MarkerSize-Specifies the size of the marker in points (must be greater than 0). In addition, you can specify the LineStyle, Color, and Marker properties instead of using a line specification character vector. This is useful if you want to specify a color that is not in the list by using RGB triplet values. See Chart Line Properties for details on these properties and ColorSpec for more information on color.
