Hello All,
I want to make lines in graph thicker. Here is my code, but it seems not working.
clear all;
close all
clc;
w1=0;
w2=16.73;
x1= @(t) 0.05*cos(w1.*t)-0.05*cos(w2.*t);
x2= @(t) 0.05*cos(w1.*t)+0.05*cos(w2.*t);
graph1 = plot(figure1);
set(graph1,'LineWidth',2);
fplot(x1,[0,2],'k');
hold on;
fplot(x2,[0,2],'--k');
hold off;
legend('x','y');
title('plot');
xlabel('t');
ylabel('d');
I am increasing the linewidth, but messing up somewhere. In plot command, you can straightaway write 'LineWidth' in plot() itself, but no so in fplot. Any comments where I messed up?

Have you tried setting LineWidth directly in the call to fplot? Both plot and fplot support Name,Value pairs like LineWidth, as in:
x1= @(t) 0.05*cos(w1.*t)-0.05*cos(w2.*t);
fplot(x1,[0,2],'k','LineWidth',2);
hold on
plot(0:0.1:2,sin(0:0.1:2)/10,'k','LineWidth',2);

Starting in R2016a, you can specify the 'LineWidth' property the same way you do for plot. For example:
>> fplot(x1,[0,2],'k','LineWidth',2);
In R2015b and earlier releases, you have to search for the object and set the line width. To set the widths of all the lines to 2:
>> set(findall(gca, 'Type', 'Line'),'LineWidth',2);
Or, to set the width of one line:
>> set(findobj(gca, 'Type', 'Line', 'Linestyle', '--'), 'LineWidth', 2);

I can't make changes through set, But I can add parameters in setting with fplot

One way is to use fplot() to get the (x,y) values, then use plot() to do the plotting and then adjusting properties via the plot handles.
clear all;
close all
clc;
w1=0;
w2=16.73;
x1= @(t) 0.05*cos(w1.*t)-0.05*cos(w2.*t);
x2= @(t) 0.05*cos(w1.*t)+0.05*cos(w2.*t);
[xx1,yy1] = fplot(x1,[0,2],'k');
[xx2,yy2] = fplot(x2,[0,2],'--k');
hold on
h1 = plot(xx1,yy1,'k');
h2 = plot(xx2,yy2,'k');
hold off;
set([h1 h2],'LineWidth',2)
legend('x','y');
title('plot');
xlabel('t');
ylabel('d');
