Question

113) Write a function “plotexvar” that will plot data points represented by the x and y vectors which are passed as the first two input arguments. If a third argument is passed, it is a color, and if a fourth argument is also passed, it is a line width for the plot. The plot title will include the total number of arguments passed to the function. Suggestion: use set function to change the plot properties. Here is an example of calling the function and the resulting plot: >> x=-pi:pi/50:2*pi; >> y = sin(x); >> plotexvar(x,y, [0.5,0.5,0.5],3)

this is using matlab

Explanation / Answer

samplecode-

function [X,Y,C,W]=plotexvar(a,b,c,d)

X=-pi:pi/50:2*pi;

Y=sin(X);

C='-m*';

W='LineWidth;,2;

figure

plot(X,Y,C,W);

xlabel('X.axis');          

        ylabel('Y.axis');

        title('Four Arguments passed');

end

note- by using above sample with required modifications the given question can be answered.
