Trying to find the function of x for 0<=x<=2L

clc; clear; close all; format short g;

%knowns
gamma = 1.4;
R = 8.31; 
m = 4.0;
P0 = 10; 
T0 = 300;
r0 = 0.01;
L = 0.05;
 
%function
x = [0:2*L];
func = @(x) r0((2*(x)/L)+ exp(-2*(x)/L));
y = func(x);
 
%graph
plot (x,y)

What is your question?

[fadams18]

can you post a snapshot of your function. what are all those values P0 and T0 for. i dont see where you have used them in the function

Rathr thn trying to use the colon operator to create x, as

x = [0:2*L];

you should learn to use linspace.

Two changes:

1. you defined x to contain exactly one value, which is not very useful for plotting.
2. you were missing some multiplications inside the function definition.

Fixed here:

>> func = @(x) r0*(2*x./L + exp(-2*x./L));
>> X = 0:0.01:2*L;
>> Y = func(X);
>> plot(X,Y)
