How do you generate an integration plot on matlab?

This is my logic:

Range = 0 - 100;

A = x-1;

B = Integrate the function (1/x^2) from 0 - 100;

C = A + B

Plot (x, C)

This is what I would like to generate a plot of; its the addition of the 2 function (C). But one of them being an integration of (1/x^2), which is being added with (x-1).

I typed something and I don't think its correct, any help is appreciated? (I am new to matlab)

My code:

X = linspace(0,100,100);

Y = (1./X.^2);

W = (X-1);

Z = (cumtrapz(X,Y));

plot(X , [W; Y; Z]);

grid on;

xlabel('x axis');

ylabel('y axis');

title('Graph');

I’m not clear on what you want to do. See if this works:

X = linspace(0,100,100);
Y = (1./X.^2);
W = (X-1);
Z = (cumtrapz(X,Y));

plot(X , [Y; W+Z]);
grid on
xlabel('x axis')
ylabel('y axis')
title('Graph')
