14. Practice questions
a. Create an anonymous function called func1 for the dummy argument x that finds the exponential of the negative one-half times the argument, and multiplies it by the sine of five times the argument. If given a vector or matrix, the function should perform element-by-element processing.
b. Using plot(), plot plotr -vs- func1(plotr) as a blue line. Then plot this same function again over the same range (0, 5) as a dashed red line using fplot(), keeping the original blue line. Label the x-axis "Plot Range", the y-axis "Function 1". Print the figure to a PDF called "Figure1.pdf". Please proof your answer on MATLAB
c. indicate which of the names below are valid and appropriate variable names.
time-history
ALL&FILES
Velocity_6
DocList
sys470_0
68_degrees
@computers_list
func1=@(x)exp(-x/2).*sin(5*x);
plotr=linspace(0,5,100);%replace this with your plotr vector
plot(plotr,func1(plotr),'b')
hold on
fplot(func1,[0,5],'r--')
xlabel('Plot Range')
ylabel('Function 1')
saveas(gcf,'Figure1.pdf')
