Hi! New to Matlab so I have no knowledge. I have some knowledge in C++ and Java and C.
I want to plot the function y=3x+2 So I guess I have to declare 2 variables x and y and plot y for a range of values of x. How do I do this? I am running Matlab2015a-SP1

x=0:0.01:20
y=3*x+2
plot(x,y)
Or use fplot
y=@(x) 3*x+2;
range=[0 20];
fplot(@(x) y(x),range)
