anonymous function and plotting

In MATLAB, define this equation using an anonymous function, for example y(ω, x, E, I, `) = ... Then use values of ω = 2.0 kN/m, ` = 2 m, E = 70 GPa, and I = 0.00012 m4 to compute the deflection over the length of the beam. Create a plot of the deflection. Run the x-axis from 0 to 2 m and the y-axis from -0.01 to 0.01 m.

I wrote this but im confused.

y = @(w,x,E,I,l)((w*(x.^2))/(24*E*I).*((x.^2)+6*(l^2)-4*x*l));

y(2,0:.001:2,70,0.00012,2)

Im having trouble ploting this.

You are essentially where you want to be. It helps to assign the output of your function to a different variable. (I use ‘v’ here.)

I am not certain what problems you are having with the plot call. There are two ways to plot it:

y = @(w,x,E,I,l)((w*(x.^2))/(24*E*I).*((x.^2)+6*(l^2)-4*x*l));
v = y(2,0:0.001:2,70,0.00012,2);

figure
plot(v)                         % Plot As A Function Of The Vector Indices
grid

figure
plot((0:0.001:2), v)            % Plot As A Function Of The Vector
grid

See the documentation on plot to understand how to use it and related functions.
