MATLAB: I want to draw a graph..

graph

I want to draw a graph of the function y=sin(x)/x. How can I do it?

Best Answer

See plot():

x = 0:0.01:10;
y = sin(x)./x
plot(x, y);

xvalues = [list all possible x values]
yvalues = [list all possible y values]
zvalues = [list all possible z values];
[X, Y, Z] = ndgrid(xvalues, yvalues, zvalues);
mask = X + Y + Z <=1;
x = X(mask);
y = Y(mask);
z = Z(mask);
f = x.^3 - log(y+z) + sin(z);  %compute everything. %use appropriate function
[bestf, bestidx] = min(f);     %or max(f) depending what you are trying to optimize
bestx = x(bestidx);
besty = y(bestidx);
bestz = z(bestidx);

MATLAB: I have a figure window down below, I’m trying to plot both (x,y) and (x,yp) on the same graph, but only one line is showing up instead of two. I’m tried fixing it, but I can’t seem to figure it out. Any ideas? Thanks.

yp = @(x) sin(x)./x; % ./
