How to plot 3 line graphs on same graph
显示 更早的评论
I am inexperienced in using Matlab and am trying to plot a graph. The function and what it should look like can be found in the pictures attached.
Difference with the graph attached is that the curve should be mirrored. In other words, for q = 0, c(q) should be Alpha1 and for q = 1, c(q) should be Alpha0.
My attempts so far have not been very successful. Any help would thus be appreciated! Thank you in advance!
I'm using Matlab 9-1

‘In other words, for q = 0, c(q) should be Alpha1 and for q = 1, c(q) should be Alpha0.’
That is not the way the formula for c(q) is written. For q=0, c(q) should be a0, and it is, and for q=1, c(q) should be a1, and it is.
The Code —
q = linspace(0, 1);
a0 = 60;
a1 = 25;
c = @(q,b) a0 + (a1 - a0).*(q.^b);
b = [1/3 1 3];
[Q,B] = meshgrid(q,b);
figure(1)
plot(q, c(Q,B))

My pleasure!
The code changes slightly to accommodate the labels for the curves.
The Code —
q = linspace(0, 1);
a0 = 60;
a1 = 25;
c = @(q,b) a0 + (a1 - a0).*(q.^b);
b = [1/3 1 3];
[Q,B] = meshgrid(q,b);
cq = c(Q,B);
CL = cq(:,40);
figure(1)
plot(q, cq)
xlabel('\itq\rm')
ylabel('\itc(q)\rm')
text([1 1 1]*0.4, CL, {'\beta = 1/3','\beta = 1','\beta = 3'}, 'HorizontalAlignment','right', 'VerticalAlignment','top')

This is as close as I can get:
x = linspace(0,100);
y = 1./(100 - x);
figure(1)
plot(x, y)
set(gca, 'XLim',[80 100])
xlabel('Service Level (%)')
ylabel('Safety Stock Requirements')
