MATLAB Matlab - graphing multivariable functions

[JoshHolloway]

I am taking a vector calculus course and am having trouble figuring out how to graph things in Matlab to verify my answers.

Here is exactly what I want to do:
I want to graph side by side two different graphs simultaneously, so I can compare them.

I will give you the equations of the two planes I am attempting to graph side by side. If someone could write the code for me to graph these side by side, then I am sure I can play around with the code and figure out how to graph other functions.

I want to graph side by side the planes:
Z = (-1/4)x + y - 19
and
Z = (-1/3)x + (2/3)y - 4

Thanks in advance!

Anyone?

Type "help subplot". This tells you how to plot multiple graphs in the same figure for convenient pictures

I have tried that, but I still don't understand how to do it.

If someone could write the code to do what I am trying to do for those two equations I gave, then I would be EXTREMELY grateful.

Is this enough? It will show you how to plot two vectors next to each other.

t = 0:0.01:10;
f1 = sin(t);
f2 = cos(t);subplot(1,2,1);
plot(f1);

subplot(1,2,2);
plot(f2);

Awesome! Thanks!

Try explot also.

ezplot((-1/4)x + y - 19) I think that should work. If not try
plot3d((-1/4)x + y - 19),x,-10,10,y,-10,10) x and y ranges are -10 to 10
