here is the code :
a = input('Insert the value of a: ');
CFL = input('Insert the value of CFL: ');
dx = input('Insert the value of dx: ');
dt = (CFL * dx)/ abs(a);
lambda = (dt/dx)
tf = input('Insert final time : ');
N = input('Insert the value of N: ');
x = linspace(-1,1,N);
%choose test case:
tc= input('choose test case number : ');
if tc == 1
u(:,1)= -sin(pi.*x)

I have just run this code in R2016a and it did not produce an error when I chose a random set of input parameters. Was there a specific set of input parameters that produce this issue for you?

Just tried again after inputting the parameters you suggested with tc=1 and did not get the error.
Apologies for asking a stupid question but in your script I assume you have the 'end' that is missing from the code in your problem description?
Also, is there supposed to be more code after the below lines? If not then your script produces no u array unless tc=1.
if tc == 1
u(:,1)= -sin(pi.*x)
