Part I: Graphing (Plot)

Generate a series x with values ranging from 1 to 6 in increments of 1. To do this type in >>x=[1 2 3 4 5 6] or x=[1:6]

Generate a series y with values ranging from 2 to 4.5 in increments of .5 To do this you can type in >>y=[2 2.5 3 3.5 4 4.5] or y=[2:0.5:4.5]

1.   Make an xy linear plot. Label axes, add title include this plot to your word document.

2.   Make an xy linear plot again. Each point should be represented by the symbol "o". Label axes, add titles, include this plot to your word document.

3. Change the axis on your plot such that x goes from -1 to 7 and y goes from 1.5 to 5. (use the axis command (zooms like google earth)) Add a grid to this plot. Label axes, add titles, include this plot to your word document.

Part II: Graphing fplot

Use fpot to plot f(x)   from -10 to 10

f(x)=x^2-x+1/x^2+x+1

Include labels and titles, save this plot to your word document.

       2) Use fplot to plot f(x)     

f(x)= 0.01 x^5 -0.03x^4+0.4 x^3 -2x^2 -6x+5

Include labels and titles, save this plot to your word document.

Part III:   Pie Plots

1)   Here is the grade breakdown for ECON 202                                                      

10 students ‘A’

15 students ‘B’

22 students ‘C’

9 students ‘D’

4 students ‘F’

Make a pie chart for the above data. Include labels, title, and section of the pie

Explanation / Answer

Part I: Graphing (Plot)

Solution:

%matlab code

x=[1:6];

y=[2:0.5:4.5];

plot(x,y)

title('xy linear plot')

xlabel('x-axis') % x-axis label

ylabel('y-axis') % y-axis label

2.Make an xy linear plot again. Each point should be represented by the symbol "o". Label axes, add titles, include this plot to your word document.

Solution:

%matlab code

x=[1:6];

y=[2:0.5:4.5];

plot(x,y,'-o')

title('xy linear plot')

xlabel('x-axis') % x-axis label

ylabel('y-axis') % y-axis label

Solution:

%matlab code

x=[1:6];

y=[2:0.5:4.5];

plot(x,y,'-o')

title('xy linear plot')

grid on

axis([-1 7 1.5 5])%axis([XMIN XMAX YMIN YMAX])

xlabel('x-axis') % x-axis label

ylabel('y-axis') % y-axis label

Part II: Graphing fplot

Use fpot to plot f(x)   from -10 to 10

f(x)=x^2-x+1/x^2+x+1

Include labels and titles, save this plot to your word document.

Solution:

%matlab code

fplot(@(x) x^2-x+1/x^2+x+1,[-10 10])

title('fplot')

xlabel('x-axis')

ylabel('y-axis')

2) Use fplot to plot f(x)     

f(x)= 0.01 x^5 -0.03x^4+0.4 x^3 -2x^2 -6x+5

Include labels and titles, save this plot to your word document.

Solution:

%matlab code

f=@(x) 0.01*x^5 -0.03*x^4+0.4*x^3 -2*x^2-6*x+5

fplot(f,[-10 10])

title('fplot')

xlabel('x-axis')

ylabel('y-axis')

Part III:   Pie Plots

1)   Here is the grade breakdown for ECON 202                                                      

10 students ‘A’

15 students ‘B’

22 students ‘C’

9 students ‘D’

4 students ‘F’

Make a pie chart for the above data. Include labels, title, and section of the pie

%matlab code

x=[10 15 22 9 4];

labels = {'A','B','C','D','F'};

explode=[10 15 22 9 4];

pie(x,explode,labels)

title('ECON 202');
